Hewlett Packard hosted the HHC 2013 conference in their own facility at 3404 East Harmony in Fort Collins, Colorado, within easy walking distance (about 4/5 mile) from the hotel which has a van for transport to HP if needed in case of rain, etc.
Fort Collins is a city in northern Colorado, about 50 miles north of Denver. Among other things, Fort Collins is famous for being the home of WWV, the most-listened-to radio station in the country! That’s because WWV is the shortwave radio station that broadcasts the continental US official time standard on 2.5, 5, 10 & 15 MHz, based on the NIST atomic clock in Boulder, Colorado. All self-setting clocks (sometimes wrongly called “atomic clocks”) listen to WWV to set themselves.
