Chapparel park, downtown Anaheim off lincoln and Anaheim blvd, rio vista park, and a bunch of mini spots down katella from harbor to euclid. You'll recognize some shit from videos.
Ponderosa is worth the skate. all the other parks arent really. All these are within a couple miles of mickey land.
Edit: If you want to recreate Ronnie Creager lines the ledges off harbor and chapman are still mostly a go, the hockey rink and his super quick 3 trick line are also down Chapman going east like a block before Haster. Angel stadium has stuff too,near the hooters theres some popular banks and a hidden one thats chill in that same area, around the way by the bus/train station theres some gnarly freeway overpass bank.
