This is by far the best way to see Boulder and the beautiful surrounding landscape. The electric cruiser bikes make it a breeze! The group makes periodic stops for historical context and informed perspectives from Russ (and occasional comic relief from Kay!). From the NOAA Earth System Lab, and the great ride down the hill, to the University of Colorado, to all the cool downtown streets, byways and neighborhoods, this tour is a must. Great people, great information, great scenery, a great experience! 5-stars!
