I like many others use my mobility scooter to tour the grounds on shifts when I'm not tram conducting. Never a negative issue in the exhibit hangars or all around the grounds. Common sense in operating the scoot is key. Don't stop and block the sidewalks, don't ride down the middle of the streets causing traffic jams and all will be fine. Don't let mobility issues keep you from attending, It's all part of the "joy" that is the Golden Years -LOL.
