I did 3 years of AFROTC and loved it all and made friends that I still have today and even run into a senior / junior classmate every now and then - kind of the small world syndrome you know.
In any case - like the rest of aviation, know what you are getting into, talk to those friends of yours, you can take the early ROTC classes without commitment (non-scholarship I believe), and give it a try.
I can't speak to the current odds of getting a pilot slot, but I do know how competitive it was back in my day, so best of luck if that is the road you chose. It won't be easy, but then again it is awful sweet when it comes to pass!
