The runways at Lowry Air Force Base haven't been used in years, more recently having been converted to streets. These massive slabs of tarmac are near mile-long strips with laughably large shoulders. When linked with other streets within the facility, they comprise a flat but interesting route of about 6 miles. A tour through the base is a short trip backward in time. This once self-contained facility was like a city within a city; it had everything. Now drab and gloomy, the buildings and hangars look vintage military of the 1940s or '50s, and they don't appear to have received much TLC for some years.
There are several points of interest along the route. Check out the old B-52 bomber and the Wings Over the Rockies Museum.
