Well your profile dose not say how big or well built your rig is???? Here in Buena Vista there are some trails that are still wide open (Pending this next snow storm) Chinaman's Gulch is pretty much open year round. Its about 170 miles from Loveland though. You would need to have some kind of lift with about 33" tires to get through it. Mine is a 99 TJ with 4" lift and 35" tires with both axles open. Not an easy trail but can be real fun if you know what your rig is capable of.
