Pretty neat stuff. I have not tried wreck diving yet, but it is on the to-do list.
For anyone that has not done night dives, DO IT! I think 3 of my 5 best dives were night dives down in Mexico around the Mayan Rivera area. Just make sure to bring a spare light, mine went out on one of the dives so I had to tether myself to a buddy
That is cool, I watched a show not to long ago on the military channel they raised a P-47 out of a lake and are rebuilding it!! too cool thanks for the link!!
