it was no longer worth it (to me) to DM for free for out of state "bucket list" divers. If I'm spending that much of my disposable income on diving per year, I owe it to myself (and my family) to focus on diving for fun.
That's really sad. I have really enjoyed meeting up with out of state people and showing them around. I can't remember having any bad experiences doing so. I consider playing dive guide to be PART of "diving for fun"!
