Taxpayers spent millions building the Colorado Convention Center and floated millions more in bonds to pay for the Hyatt Regency Denver across the street. Now we know why: Their bathrooms are easily accessible and stay open late for anyone who's been kicked out of a nearby bar, doesn't want to use the alley, or needs a toilet quick. The first-floor loo at the convention center is usually open until 9 p.m. on weekend nights when something's going on there. After that, use the always-clean privy (the concierge insists on calling it a "restroom" rather than a "bathroom") in the Hyatt, which is in a spot where no one will notice that you're not a guest. Talk about tax relief!
