In the Chip there is lots of junk, new and old bikes, a few old cars pipes, fish, old bridge inbutments. The current is pretty quick so there is always new stuff being washed in and out. I don't normally see the same stuff on most dives other that the 2 cars at the end! I once surfed across the bottom on an old 6' dock bumper that must have been off a huge boat. Last year I looked over at my dive buddy as he was riding a brand new looking bike down the river lol. Its a fun dive and you don't have to work as its all drift. I would recommend doing the dives with someone that has done it though. Its also kind of hit and miss with viz, this sunday that just passed we didn't dive as the viz was about 3 inches. The week before it was 15' foot.
