jane, you're 2 hours from me or so once i hit school (london).
what do i do? well im in a small town, and i quickly found the musicians (occasionaly playing guitar at school, already knowing people then finding out they were players), i had it easy i suppose. once i get to college, im basically going to be like "guitarist looking to jam with ANYBODY! facebook/call!" and see what happens.
basically you have to go and find them. put up ads in music stores and CD stores, go to open mics, and if you hear someone playings omethign cool at a guitar shop, talk to them! also attend concerts and chat it up with people, that helped me meet musicians from just outside of my town.
