Found a fantastic place just South of Barrie called Centenial Park. Ten Sideroad and 7th Line, very close to hwy 400 and Innisfil Beach Rd. Not a very large park, but very secluded, good view of the parking lot so you can see if anyone is approaching. The best part is that there is a giant pavilion so you can get out of the weather. Have been there 3 times now and have had fun every time. (twice met up with dogging couples) It looks like this is a great parking place for both couples and cruising men. (have seen guys in there both in the morning and night. (thinking the best time is around 4:30 onward but could be wrong) Give it a try
