I wasn't able to break away from the family activities long enough to dive Sarnia on Sat, and there was a storm that rolled through so I figured the river would be bad on the sunday.
giloba is a great quarry,... my first dive of the year was there, Easter weekend, it was snowing out (a bit) but the sun was bright and the water was 34,... great wet suit weather. Myself and my dive buddy were the only ones in a wet suit. Still got a 35 minute dive before it was too too cold.
the plane was great. I'd love to go back there again, soon.
Mike the owner is a great guy. I imagine it's insane there with number of people that come in the summer. I think late fall would best there.
have a good one
