I don't know about WMU 82, up the Bruce, but around here the best time to get frogs is on a rainy night back of Verona, there are hundreds of them on the road. Some are not so thick any more, but the ones that only got run over once are still pretty good.
Best frog legs I ever ate were in Algonquin Park around 1982, caught them with my hands. Second best were frozen frog legs I bought in a grocery store in Westport Ontario and I believe they were a product of Vietnam. Like these ones: https://www.wagjag.com/deal/toronto/30-off-frogs-legs
But anyways, having eaten a lot of frog legs from frogs I personally caught, I can say with 100% conviction that it is a heck of a lot easier (and cheaper) to buy the frozen product.

and BTW Huck, being an ignorant prick on here is not a good way to make friends and influence people. Just sayin'
