For those who love hills, the Tour of the Wichitas has been scheduled for May 2nd. From the website:
A beautiful ride through Ft. Sill and the Wichita Mountains. You will be leaving the Museum of the Great Plains at 8:00 a.m. on Saturday and riding either 2,10, 40, 50 or 60 miles through some of the most beautiful scenery in Oklahoma. We will also have a historic route by the Ft. Sill Museum and some of the most important historical properties at Ft. Sill. The longer rides will have a water stop at the Visitors Center in the refuge. You can pause here and learn about the make up of the refuge along with what types of animals it supports. Also the location of the hiking trails and fishing lakes. From the Visitors Center you may ride back by Mt. Scott through Medicine Park, or on a breathtaking downhill that will pass the Meers Restaurant and loop around Lake Lawtonka back to Lawton. This is a smell the roses ride. Take your time, look around and enjoy!
