Hi Ron,
I'm in the Wilmington, NC area; however, I know where Pembroke/ Lumberton area is. It is definitely a hot and humid area. I'm thankful we do have an ocean breeze in the Port City. As far as mountain bikes, I have a Diamond Back WCF that is getting old. I've asked some advice on it, but I posted to the wrong forum.
Decater, Ga. ? I visited there a few years ago when attending a conference. Any good trails around that area?
