Ep 4. 2WD Motorcycles Taking on the Idaho Wilderness With Chainsaws! 

Zack Courts and Ari Henning are off to Idaho, where winter weather ruins motorcycle trails every year and it's up to State Trail Rangers to fix the damage. This time on Throttle Out, with the help of a couple 2WD motorcycles, the boys become honorary Rangers and head into the Sawtooth Mountains with the hope of opening an especially gnarly loop.
