Don:
What is that dog doing to that tree?
Why is the dog wearing a glove?
Why do you have this picture?
You Texas folks have a weird idea of pornography.
It looks like he is hugging it, as tree hugging was mentioned. I don't see porn. It must be you.
I find all of this permitted and not permitted stuff interesting if not confusing. We just returned from CZM yesterday (had a great time - again). Before we departed the US, I checked the "latest" restrictions posted by TSA. After some research, it seemed that lithium batteries were suspect but, after inquiry, was told to transport in original packaging (to eliminate the possibility of the battery terminals contacting). I needed batteries for cameras and dive lights. So...I took 6 AA alkaline batteries and taped them side-to-side with masking tape, packaged AA lithium, and 2 sets of 6 AAA alkaline taped side-to-side. I put the lithium AA in the checked bag along with AA alkaline. I put AA alkaline and AAA alkaline in the carry-on bag along with the regulators/computers and clothing. Upon departure from PHL, the TSA attendant manning the carry-on scanner went ballistic when viewing my bag and immediately called for the site supervisor. The supervisor arrived and said "that's nothing but scuba gear, they're going diving." Not a word about batteries. We returned with basically the same packing regime. In CZM we were told of and shown a printed list of forbidden articles for carry-on at check-in. Batteries were listed. We decided to take our chances. Our bags were scanned and not a mention of batteries upon security scan. We continued on our journey home. I think some individuals may trigger scrutiny by their appearance, behavior or demeanor. Be smart, travel light and be polite.
I think many of us experience a lot of extra scrutiny with our carry/roll-on bags containing gear and photography supplies. I try to stay handy when leaving Lubbock in case the checked bag screener has questions. TSA rules say my pony bottle must be open but that's just stupid to allow debris to enter it, so I tape it with 2" electrical tape, ends folded back for easy removal, and that has worked well on dozens of screenings. Some of the agents do ask about my blue moisture munchers in a ziplock of Damp Rid, so I explain. I do make sure I never, ever let lawn fertilizer come in contact with my bags and gear; I've heard that golfers have a lot of problems from that kind of residue.
Traveling with batteries gets trickier as there are different rules for different kinds.
"As of January 1, 2008, the Department of Transportation (DOT) through the Pipeline and Hazardous Materials Safety Administration (PHMSA) no longer allows loose lithium batteries in checked baggage," but there are differences in lithium batteries...
There are additional rules just for
larger lithium ion and
lithium metal batteries. What are
"Larger" lithium ion batteries? What are
"Larger" lithium metal batteries?
Lithium metal batteries are non-rechargeable batteries you discard once they are depleted.
Larger lithium metal batteries contain over 2 grams of lithium, and are forbidden.
Most consumer
lithium metal batteries such as AA, AAA, and CR-123A sizes, do not fall into the "
Larger" category. Just follow the
Basic rules.
Lithium ion batteries are the rechargeable batteries used in computers, cell phones, and other devices.
"Larger" lithium ion batteries are rated between 100 and 300
watt-hours (8-25 g
equivalent lithium content, or ELC.)
Leaving Mexico for the US is just different, and carrying spare batteries in carry/roll-on bags is just inviting trouble. You can chance it if you wish, but in discussing safer options - I wouldn't. I stick to alkaline and NiMH mostly and always stick them in checked bags, which neither Mexican security nor TSA prohibits. It does help to pack them in nifty battery holders available at Thomas Dist, Amazon, etc. See
Battery Holders and Storage Cases for a nice variety and prices. I got a lot of AA/AAA holders free with NiMH purchases there. I
always have a couple of AAs in a holder in my cargo pants pocket (calling them grenade pockets is discouraged around airports.
) for quick changing - came in handy at my grandson's graduation.
Some suggest bringing used alkalines home so they don't end up in local landfills, and I do recycle those at home, but I often leave them with my dive Op if he seems interested. Mau said
"We like leftovers" as I gave him batteries, a coffee maker and part of a bottle of coffee liqueur.
The NiMHs I want to bring home and use again & again. Going, I have the alkaline batteries still packaged in their original, retail containers - but returning, I leave them.
