living in PA with out of state license

[drew]

I got pulled over tonight playing around in my tibby after installing a CAI yesterday ( first mod in virgin car, just got it friday ) anyway, I got off with a warning because I'm in the medical field. However, the officer told me he could/should have arrested me because I failed to get a PA license within the alowed time frame (wich he wouldn't tell me what it was)

I've lived in PA since January, and I have current in-state insurance, but my license is for WA state and doesn't expire until 2010, I was just going to wait until 2010 to renew it and get a PA one because noone ever said I had to get a PA license... was the cop bluffing?
