Rocky Mountain Audio Guides, which produced a CD titled Walking Tour of Denver's Historic Lower Downtown
expanded its reach last year with a cell-phone hookup. Founder Barb Rigel's idea was to have folks who might want to tune into the cityscape dial a number, enter a credit-card number (for $15), and then listen for up to eighty minutes as a recorded expert tells them where to go in LoDo. While the CDs are still available at places such as the Tattered Cover, Rigel hopes this will allow folks to get even fresher insights on places such as Skyline Park. Good call!
