My first airsoft game ever was at Muskoka - I was the scout for a night game leading BlackBear around the field. Prior to that I remember running rolls and rolls of blue tape through the woods for the UN game. Those games, everyone, was truly memorable and full of excellent stories (some were even true).
Unfortunately, I am missing some memories (possibly due to Vodka) and have been told I can take out a very large man in a single bound!
Anyone who has not been there is truly missing out on a great experience not offered by any other field.
