Hi Hash,
My friends and I live around reading/wokingham and we play at Gunman (Eversley) and Red Alert (Thatcham/Newbury).
Both very well run sites with friendly staff and good grounds with decent and friendly regulars. Walk on or hire is available at both.
Gunman do a skirmish weekend normally in the first weekend of the month and a film sim weekend in the middle weekend of the month, either at their Alpha or Bravo sites (Gunman Eversley has two sites).
Red Alert do a single day skirmish every weekend, alternating between Saturday and Sunday.
Gunman have a skirmish event this weekend with plenty of spaces left if your free this weekend.
Hope to see you there some time.
