Colorado is a great place for people who love the snow and the mountains. You can go skiing, travel up Pike's Peak, visit the sixteenth street mall in downtown Denver, and many other things. If you want to avoid the snow, then travel in the summer months(June, July; August). If you have asthma, the mountain air my help to reduce or eliminate your symptoms. When I lived in Denver for a few years, I never once had a problem with my asthma. The parks in Denver also have geese. So if you like geese, then pay these parks a visit. Parks located in Lakewood(a suburb of Denver) are more likely to have geese than the other parks.
