Played at Flagraiders in Cambridge, Ontario....had a good time at Flagraiders although in the dead of summer there is no shade and some of the other players (appeared to be regulars) on the field had questionable paintball ethics....I've yet to have issues with any players at Barrie.
Played at DMZ in Niagara....super nice staff although the fields are small...Barrie has spoiled me with big fields.
Played at Wasaga....good staff and good fields but WAY too much hiking about to get to fields. In Barrie you go onto field and generally play two games then return...in Wasaga you play one game and return so alot of time is spend hiking to fields instead of playing.
From the first time I played at Barrie I was impressed. It's a very large, wooded and nicely set-up field. Great staff, good prices and I've yet to have a bad experience there. The referee's are great and very fair and the owners are consistently adding fields and props to the fields.
I don't even mind the 1.5 hour drive to get there as it's well well worth it...I highly recommend this field.
