Went here during the Friday walk-in hours and had a blast! Wes was the main guy instructing us, and he was really nice, offering tips to us as complete beginners. The staff clearly took safety seriously, but also wanted everyone to have fun. I can see how this place would be attractive if you're with a large group, but it was fun even with just three of us throwing axes for an hour or two.
One warning - be sure to stretch first! (Especially your shoulders and sides/core.) It's more athletic than you'd think. Also, they have a water cooler where you can get free cups of water when you're not throwing. You'll definitely need it! We were really thirsty after our session.
Definitely check this place out if you're at all interested. You'll have a great time!
