Doncaster State Park is just off RT. 6 in Nanjemoy Maryland. This is a cooperative ride with Friends of Doncaster. The poker game on horseback is simple. As you ride the trail, you will find colored bags that have an bunch of colored envelopes. You collect one of each color and leave them sealed. Once you get back to the registration area, you will get one more card. You then get all the envelopes opened and see what you have in your hand. The poker hands winners are judged via standard poker rules. When the last rider get back, the final winner is determined. The winner receives 50% of the collect pot. In the mean time of waiting for the last rider, you are welcome to enjoy lunch with your MAHA family. Food is available, donations are accepted.
