Great Lakes Aquarium- volunteer divers

Either or.  I have a 7 mil farmer john.  It's sufficient for an hour or so at 53 degrees.  I just tried my new drysuit a couple of weeks ago.  It's so nice getting out of the water and you're dry...they're great!

Concerning the comittment to 200 hours...I think they're a bit flexible on that one.  It takes alot to get checked out through them, and they want to make sure their money spent is worthwhile.
