GW Highgate is one of the busiest places to play that is open all the time [well, not
all the time, but you know what I mean]. Monthly events like CHOP or Trumpeters are bigger and busier, but may cost money to join, and only happen a few times a month, if that.

I myself am organizing a large, semi-apocalypse game next month, taking place at
GW Highgate. It'll be a free, casual, intimate battle, and only need to bring up to 2500 points [you can bring less]. If you're interested, you can message me, or reply to the 'Last Stand at Metrogate' post on the
BC Wargamers page.
