Group/team activities in october? [sERIOUS]

Hi! I'm organizing a conference in Kamloops in mid-October. Every year, we have an event night for some team-building and good old competition. About 50 people attend, mostly tradesmen.

Last time we held the conference in Kamloops, we bowled at Bowlertime and had a...memorable experience... at the Dirty Jersey. I'm looking for some alternate options for an evening event, though I'm aware that our choice of date generally excludes a lot of outdoor activities.
