I love the rockie mountains, but if anyone in your family has asthma or lungs that are compromised, just be cautious of the higher elevations. Both my husband and my sons had lung conditions and had some unusual reactions. Husband fainted on me during one visit (stayed hydrated the next visit), son had asthma episode during one trip - fortunately I had prednisone, ventolin aerosal treatments with us. Both were pretty scary, because they were unexpected reactions. If I had been prepared, it might not have been as scary.
