Boulder and Denver share a common mass transit system, known as RTD (http://rtd-denver.com/). which won "Best Public Transportation" in a nationwide survey in 2008. You will also notice that a large percentage of locals use bicycles to get around the down town most of the city sights are within 2 miles. If you choose to drive around town, be aware that there is heavy traffic on the main thoroughfares, high numbers of pedestrians cyclists and parking downtown can be a bit tight. There are a number of city-owned garages tucked behind the buildings downtown. Keep your eyes open for the large green "P" signs outside their entrance ramps, as they don't look like parking garages from the outside. Be careful when parking in the University area, as tickets can be quite expensive. Boulder's police are vigilant about drunk driving, so try to keep out of the car when you find yourself tipping down a local microbrew or two. Watch carefully for the school zones: when the yellow lights are flashing, slow down to 20 mph! Many of the main streetlights have cameras that can capture you running the tail end of yellow lights. Watch out, or you may get tickets in the mail!
Many locals use the "Skyride" RTD bus to get to and from the airport. It's greener and easier.
