After four years of sweat, dirt and exhaustion, a substantial effort to rehabilitate three miles of trail in and around the Alberta Falls and Lake Haiyaha area of Rocky Mountain National Park has been completed.

On September 29, National Public Lands Day, the National Parks will celebrate by waiving the entrance fees to all national parks. In addition, thousands of national park lovers will volunteer to protect the promise of the Civilian Conservation Corps (CCC).

If you've ever stood in the middle of the National Mall in Washington, D.C., you can imagine what a chore it must be to cut the grass, trim the shrubs, prune the trees, and keep the flowerbeds tidy. And mowers, clippers, and trimmers for that sizable task aren't cheap, which is why Honda is being applauded for donating more than $70,000 worth of power equipment for the job.

A "red rock" ride through a national park is coming up September 29, but you'll have to head north of the border to participate in it. That's when the Red Rock Parkway in Waterton Lakes National Park will be closed to motor vehicles for a while to give cyclists clear sailing.
