We run all winter long.
Usually at least one outdoor game a month. If it's chinookin' out maybe more. Games are usually planned a week or so in advance and if its no lower than about -5 the game is a go.
We ran an outdoor game last January because people were jonesing to play, it was -20. The only thing that had an issue with the cold was batteries. Run a lower fps gun or a springer (ie:bolt action) and you'll have no issues no matter what the weather. Don't bring anything gas powered out to play if it's less than 10.
