Artificial mountain
This is as close as I get to a mountain during my work week in Kansas. It stands a total of 215 feet high. So far my record is 2 minutes, 30 seconds from bottom to top. Climbing it this fast usually gives me touch of LAPE (Low Altitude Pulmonary Edema!) and I feel like I am having an asthma attack - fortunately it passes in 10 to 20 minutes.
