Hello fisherman: I just got back from a trip last Wed. I would have camped in the backcountry, but about 11 days prior to heading out, I was told that the lakes were not frozen over, and that grooming on the dog sled trails hadn't even started. I ended up camping at Mew Lake for eight nights. As it turned out, the dog sled trails were up and running shortly before I started my trip. There is less snow in Algonquin for this time of the year.
Take care,
Cousin Pete
