my vote goes to keystone. sick jumps, sick rails, smaller lift lines....my only gripe is sometimes the rail placement doesnt make sense (that upbox at the beginning of the pocket park, cutting across features to get to other rails)
breck...freeway id deff very very very legit, parklane on the other hand....i find myself constantly overshooting their shit, they have down rails/boxes and dfd's with tall gap on lips, why not urban?? and yeah, the whole lift situation at breck sucks...
dont forget about the bastard step-brother park, copper. people in summit write it off cause they are spoiled with key and breck, but shits super fun right now, still one of the best parks in the country, and woodward is opening in two weeks, PM me for info on that shit
