Might do a three day weekend trip to Colorado for scouting and shed hunting in unit 18. I was planning on packing in with a small tent and sleeping in the woods unless some people tell me its to cold at that time...? Or.... roads are not clear yet?
I've slept out in a small tent off the back of an atv in late April to early May in the past during turkey season up on the Uncomphagre Plateau. Long as you have a warm bag you should be fine. Just remember some of the forest road gates to the higher country don't open until late May to June 1st.
