I got back a while ago from a night dive to the OJ Walker wreck in Lake Champlain.
What an awesome experience!  58 feet deep, the wheel house still in tact!  Very awesome!  For the records, at 58 Feet the water temperature was around 52 degrees.  
The boat was carrying bricks from Malletts Bay to Burlington when it sunk on May 11, 1895 in the Burlington Harbor.   Awesome to see!

Thanks to Wade for taking me along on this dive!
