The Katy Trail, a 3.5-mile paved path that stretches from Uptown to Highland Park, has a lot to offer — dense trees and foliage that keep summer temperatures to a modest 105 degrees, a wide track for walking your dog or walking slowly abreast with three friends. (Gotta remind those runners and cyclists to slow down and smell the roses.) A slow pace is also good for one of the best Katy Trail bonuses — window shopping for a town home or apartment, or maybe just picking up a few decorating tips by peering into the windows of the homes that line the trail. Besides, why would anyone want to fly by the crowd that assembles on the route around 6 p.m. after a long day at work? Intimidatingly good-looking urban professionals pump their toned legs, do sit-ups and push-ups on the trail side and bop their heads to the music in their earphones, totally at one with a bit of nature in the heart of the city, and completely deaf to the calls of "on your left" by cyclists, runners or anyone with a heart rate above 85 bpm.
