Permanents
How is the Permanent situation in your area? Permanents are basically Brevet routes maintained by the RUSA and can be ridden virtually any time. I live in the Dallas, TX area and we have a fairly large collection of permanent routes to choose from with several new ones added so far this year.
The Lone Star Randonneurs is a very active Randonneuring club in the Dallas area. It seems that almost every weekend, a group gets together to ride a permanent. This weekend, there are groups riding different 200K routes both Saturday and Sunday. Lot's of opportunity to get RUSA credit for riding.
