Just played this field last week. I agree that the people in charge have good knowledge and keep it safe. I also agree about the poison ivy. There are lots of open paths between forts/bunkers but there are areas of this field that are still very overgrown and thick. Can be a plus or minus depending on how one prefers to play. Turnout was around 18 players, which made for some slow playing at times, but they shortened the field when needed to make it more interesting. I will definitely go back.
One thing I will add: it is very hilly, so be prepared for some inclines! And in some of the thick areas, ground cover hides small drops and holes. Those with weak ankles will definitely want to wear some high boots.
