You'll go to the nearest MEPS if you enter the military regardless of how you come in. I'm lucky to be near one - while I was at MEPS in Utah I had other guys processing from Las Vegas and Idaho.
You'll have to ask your OR about the PRT, but I doubt they'll let you get away with it.
I'm confused, though. My first OR was a 2-hr drive away, and I felt I was lucky to have one so close. The next one was in Miami, 5 hrs away. That might have been rough, but 2hrs isn't bad at all. My current recruiter is 10 mi away, but it was a 50 minute commute before I got my car.
Point being, are you hard up for transportation, or perhaps working full time? A two hour drive is a real small hurdle for something like this.
