I started skydiving last year and recently made a trip to PST to do some coach jumps.
The DZ (drop zone) is located just northeast of Newmarket at Baldwin Airport, a small grass strip. Turn down the road, drive all the way to the back, and look for the big hangar.
The staff (especially the operator, Adam) are great people, they have the genuine (though often a little weird) sense of humour that you can expect of skydivers. That's just how we are. If you're coming for a tandem, you'll sign some waivers (don't be scared, it's standard stuff) and watch a quick video of Bill Booth explaining how tandem skydiving works. Then it's off to meet the instructor you'll be going up with to get harnessed up, briefed on how it works, and up into the aircraft. Then you'll get hooked, and you'll be talking to Adam about PFF and getting licensed.
Seriously, plan to jump twice, if you're a new tandem... the first one you won't appreciate as much, the second you'll love.
PST doesn't have a turbine aircraft regularly, but their Cessna still gets up pretty quickly, and the view of Lake Simcoe and the area is pretty beautiful.
For fun jumpers, the crowd is great, the prices are decent (top shelf for $35 cash price as of last week), the landing area's great (they separate students/A-licenses and B/C/D-licenses into to landing areas), and there are places for food and drink close by. Definitely a great option, by all accounts far more accommodating than STI.
