The field is located right on the property of the Gibraltar Trade Center in Mt Clemens. Drive through Gibraltar's main gates and they're on the left hand side of the parking lot.
Just played out at the Lone Wolf East field last weekend with a few of my buddies and had a great time. Now through the end of March they are running a winter time special so everyone gets membership pricing. With the special it was only $20 for BYOP and all day air (nitro or CO2). If you need to rent equipment, with the special it is free. All you have to do is buy paint there.
One of the guys out there told me though that on Saturday March 31st from 10-4 they are holding their annual Work Day. He said if you work for the day you'll get a free one year membership so you can get discounted playtime, air, paint, and 10% off at their pro shop in Macomb all year round. I've done it the past few years and let me tell you, it is totally worth it! He said the next day, Sunday April 1st is their official opening day for the new season. Games will be every Saturday and Sunday from then on out from 11-5.
I've been playing out there the past few years and always have a great time. There's always a good crowd of regulars and the staff there is really cool. They're always in a good mood and like to mess around but are still strict with the safety rules.
