My house is at about 1240 feet above sea level. My favorite mountain bike ride starts at 1800 ft. and climbs to 2700+ ft, with an awesome twisty-turny mogul type downhill rollercoaster ride that can't be beat. My current favorite road ride starts at 2300 and climbs to 3100, with a wheeeee downhill most of the way back. Can you tell I like to work hard and then reward myself? Those are the best kind of rides!
