I can't remember if it was Blackhawk or cripple creek but in one town all of the casinos are on a huge hill. Fortunately my hotel was at the top. The bad news is that I started at the top and worked my way down. Once at the bottom I then had to walk all of the way up. My poor asthma afflicted lungs barely made it. BTW - when you are there be sure to drink lots of liquids or the altitude sickness will give you the worst headache ever. Beer and mixed drinks worked of me
