Justatroutbum - My best advice would be to contact the park service to check on the time limit for parking. I cannot see that it would be a problem, as that is a jump off point for backcountry trips frequently...

BTW - I was on that trip with Byron - we were all dead, but it was SO worth it....Will never, ever forget the exhilaration of reaching the dome parking lot after having come up from campsite 71 on Springhouse branch and then Forney Ridge Trail.... :P
