My Son and his Lady Friend, bought a 2010 People 150 in June and in September riding two up with saddle bags, suitcase, sleeping bags, and tent; they rode it from Central Minnesota to San Francisco, CA. They averaged 50 mph to not beat the scooter. They crossed the Rockys in Colorado at 10500 feet only able to do 35mph max. They had to buy a one gallon gas can to cross Nevada driving down the Extraterrestrial Highway. It took 7 days (2 days in Mitchell, SD due to heavy rains that actually flooded two small Minnesota town the following days. He said southern Utah was absolutely beautiful and fun to ride. Nevada was hot and boring. Not sure if they have feelings in the butts yet, but are very happy to be in SF and were very pleased at how well their little scooter ran.
