I guess it would depend on how things ended with your friends? what happened in between... where they are are in life. People change. Relationships change... that's both a good and bad thing.

I would think it's worth a try... things can be rekindled...
I guess what I'd ask is do they still live nearby? Are you still interested in similar activities, etc? If so... then there's definitely a chance I would guess, and if not, it would be harder but if you want to try go for it
