This is the best outdoor field in the Ottawa area.
Commando Dave (the owner) is a real character and my experiences with the staff have been mostly positive.
The field is safe, but they don't go overboard on rules. I find the refs are good about customizing the game to fit the preferences of the group.
The fields are quite well maintained with a good mix of forest, bunkers and forts. My favorite by far is the large forest field. There is plenty of room for flanking maneuvers, which encourages a more aggressive style of play.
If you are in the Ottawa area you should check it out.
