If you are wondering about the fire bans here is a link to the county by county bans in place here in CO.
CO is so very dry, please show extra caution. I have followed behind people who have thrown cigarettes out of their car windows. Please, please don't do this. Use your ashtray. Also make sure your campfires are completely doused.
And with the July 4th celebrations approaching, it's important to note that CO doesn't allow a lot of fireworks that are legal in WY so don't bring them into the state. If you are going to be in the Denver area on the 4th a great fireworks show can be seen in the Englewood/Littleton area at Cornerstone Park. It's one of my favorite shows with activities going on all day for the family.
