Well, so far my favorite park is SFMW, but PGA and SCBB are also up there on my list.  I go pretty much every other weekend.  I've gone twice a week to at least one of the parks a few times this year.  Especially SFMW with V2, I just can't get enough of that coaster!  I'm going to IOA, BGT, SWO and Disney/MGM in September, and Knoebels and Dorney in October for the Phunfest, so one of those parks could very well become my favorite.  :)
