New to area.

I'm from South Jersey but my son goes to Muhlenberg and I'm coming up on Friday and want to get a ride in with him. I'm thinking about Salisbury. I've been at this for about a year so I'm not a novice but at 51 I'm no shredder either. My son is a beginner but has the advantage(?) of youth. I wanted to know if Salisbury was a good place to go and what trails to take for my ability. I rode Blue Marsh this summer with some of my middle aged friends. We did the 25 mile loop but it kicked our ass. Any info would be greatly appreciated. Thanks.
