Can't think of the names right now but I have played at a couple in the Portland area
Woodland Paintball
Directions to the Field:
N on 503 about 5 miles
Turn E on Gabriel Rd. Go about 3-4 miles.
When you get to the T in the road at Gabriel and Kelly...it's right in front of you.
Review:
This is a great field for all players. They have a great safety policy. The refs are good. Very friendly. Not sure on the hours of operation. Cost is about the same as any other field out there. I don't know of a "proshop" there but they do have some tools (not a lot) that you can use to owrk on your gun if you have issues.
