We regularly go to family reunions at Whitney each October, and I can tell you that the current runway is tiny. Anything larger than a 152 is going to find the landing difficult. There is a discontinued runway there that is about twice as long, but because this is a state park, they didn't have the funds to keep it open. My uncle had been flying there for years, but hasn't since they shortened the runway. It's kind of funny watching planes circle the runway 4 or 5 times and then finally making the decision that they just can't make it and head to Waco instead.
