I never get it why people put their gear away for winter and don't play during the BEST times of year to play paintball... In the SNOW. Nothing can compare to the silence of the woods after a thick snowfall, the burst of gunfire will shock you with how loud it is. And just walking between camps is hazardous as the snow makes everything so slippery.
So when you fall (and you will) just keep your hands up so you don't sprain your wrist, and fall on your back. But, get out there and PLAY some paintball!
(all markers used in this video were Tippmann's and all of us but one guy were using Co2. The other guy was using compressed air on his Phenom).
These are some STEEP hills and trying to get around in 12 inches of snow will WEAR YOU OUT, but the fun is worth it!
