Maple Ridge - IPG Delta Force Paintball - HPA Tank Policy
Their policy is to not allow owner's tanks on the field. I was told it was an insurance issue. So don't believe the call centre if they say it's okay. They are not the boots on the ground in terms of the Maple Ridge field.
For any special exceptions, one must talk to the field manager.
This information is based purely on my experience as someone who went there to play.
