1) No regulations about "carrying" a chain saw. You do have to have a permit to cut firewood. You won't have issues if it's for clearing a forest road. Fire bans are going to be your biggest concern, so you're most likely not going to be allowed to have an "open" fire. It's been relatively wet in Denver and the high country, but it doesn't take long at all for things to dry out. 2) Colorado is an open carry state. If you have a Concealed Handgun Permit from your home state, check the reciprocity rules as I think VA is a little different than most states. I believe that VA recognizes my CO CHP, but CO does not recognize VA's. Verify it yourself though. If you're driving, you will also need to check about the state's handgun laws that you will be driving through as well.
