There's nothing that can be done about Maple Ridge unfortunately. The new paintball owners don't want any airsoft, at least that's how it's understood. There's other Lower Mainland paintball places who've banned airsoft as I understand it as well.
The new owners of Panther, Milsig, are making positive changes and we all expected and accepted that cost to play would go up. Honestly, and compared to other places in Canada, $10 - $15 was pretty cheap. I personally have no issue with paying a little more, but with the added corkage fee so that I could use my own BB's, my day came to just under $34 to play. Too much in my opinion. I'm sure Milsig will continue to make changes and they have guaranteed us that they'll bring in more BB brands, such as Bastards, Elite Force, etc. So we'll just see I guess.
