Hey Spark -
Belleville, Picton, etc. is one of our favourite places to go - especially in the summer. Suzanne & I are going to be in Picton the week of July 18th for a few days.
The entire area is known as "The County" - Prince Edward County. That's from below Belleville - the south side of The Bay of Quinte and taking in the entire area. Not a lot of twisties and hills, but nice two lane country roads. Lots of wineries, antique shops, and relaxed living. Plus Sand Banks Provincial Park - kind of a small version of Ipperwash or The Pinery.
Whay type of events are you looking for? Picton has started developing some Jazz and Blues clubs from what I understand, and there seems to be frequent car shows and rides on weekends.
Someone else had mentionned some good roads north of Perth, and there are some great rides through that area. I used to ride a motorcycle, and we never tired of these areas for twisties and hills.
Thanks again, Spark - let me know what you're interested in.
John
