The influential cities have all been named, great work team. We can move on now
Idk man sometimes I create threads in the hopes that it will just generate an interesting discussion rather than just people naming cities or whatever. Most likely it's on me to put more effort into fostering the discussion though instead of just hoping it will happen organically, The issue is I'd generally rather just read other people's opinions than my own most of the time because I'm not even half as knowledgeable as some of the posters on here about skating.
Philly is a great example. Obviously there is (or was) Love Park there which fostered all kinds of tech skating in the 90s but you've also got FDR in Philly which if I'm not mistaken was the first big DIY on the east coast and is arguably just as infamous as Burnside.
And then Burnside leads into Portland, which I think is also a great response. I think the influence on skating that came out of this city is hugely underestimated. I mean, it's the first place in America where there was a skatepark built by skaters and this spawned two of the most highly regarded skatepark builders in the world, Dreamland and Grindline. I wonder how much influence over street skating this city/area has had though.
A couple people mentioned Sydney, and while I love the city and can absolutely acknowledge its place as a cultural hub for skateboarding in Australia and arguably moreso than Melbourne, I can't really see how it has been influential on the international level of skateboarding.
