The site at Bricket Wood might be alot easier for you to get to, its next to St. Albans. Its open every sunday. Pay £15 entry and play for the day, buy paint on site or bring your own
Its a site with a sup'air field, although the owner is commencing work to upgrade it all and eventually have 4 fields up.
Qute a few local teams train there, and its a good chance to get playing sup'air, meet new people, and have a laugh.
