>Brampton Flying Club to the North has a huge fleet of Cessnas.
Well I don't know if I'd call 20 planes a huge fleet. I guess it's all relative.
There are also a " huge" number of pilots there, so you usually need to book a few days in advance at least. Still, it's a great place to fly from, although I haven't flown from anywhere else and can't really compare :/
I don't think Brampton's rates are any higher than anywhere else.
