I'm a 5'9" adult male and I use a Razor scooter! There, I admit it. I occasionally work nights in a hospital and I get bored. How do I occupy my boredom you ask? Well I get on my Razor and start gliding through the halls. I'm sure I've been caught on security cameras roaming the hallways. But so far no security guards have come to stop me. I bet they wish they had one for themselves. My only wish is that the handle bars would telescope up a couple inches higher. That way I wouldn't have to stoop down to hold the bars. Yes, I know....this was not intended for adults....rather for children. But come on! I know you're out there too. I'm not the only one who wishes this!
