Jim, I have to disgaree with you a little bit. The dangerous ice conditions on Lake Erie are well known to local fisherman. It's more like an ocean than a Lake. The ice sometimes piles up 30-feet as the various plates drift into each over, so the unstable nature of it is apparent to even a newbie. My friends and I recognized how dangerous it was back when we were 7, 8, 9, 10 years old. We were allowed on the ponds, but not the Lake (we went anyways a couple times and scared the @#%# out of ourselves).
Lake St. Claire is a big Lake, but an entirely different beast than Lake Erie. It actually freezes over many winters (or at least did in the 70s). Bob, remember the snowbile races on the ice and the parking lot of cars out on the Lake ('74-77')?
