Technically, the PHA requires you to have their hillclimb license.
I called about that at the Duryea event last year. I have three current wheel-to-wheel racing licenses (VRG, EMRA and NASA), a current race medical and experience at previous hillclimbs (Hershey).
The offical I spoke to said I'd have to come the day before (Friday) and go through a school they were running. I was sort of surprised by this but didn't argue. I would not have been able to come on Friday due to work. He also told me they'd have to check out my car (which had two current logbooks) and this was too complicated to do on Saturday morning.
I respect other clubs rules, so of course, I just came with my street car and spectated that day. While I was there, I ran into several guys I knew (one was an offical of the club) and they all said I could easily have run. They told me that the offical I spoke to is "cranky". One guy pointed out a fellow who showed up that day and had never run a hillclimb or race before...they let him run. Kind of annoying, but what can you do?
Anyway, the technical answer is, yes , you need a hillclimb license and *may* need to get to an event a day early for a school if you wish to run your first event. You might want to check out the
