When you say upstate how far are you exactly talking about? I grew up in Plattsburgh so my upstate is different than the NYC version of it. Saranac Lake has a newer nice little concrete park and Plattsburgh has a diy that may or may not be in a decent state ( it's been a while since I've been back ) but I'd cross the lake to Burlington VT and hit the A-Dog Park, the diy behind Burton, and the Burton bowl. There are also a handful of other parks and spots in and around Burlington. If you're only making it as far north as Albany that new park they built looks pretty rad
