Dogs and their human companions both find the Paul Carr Jogging Trail that runs through the Heights Boulevard esplanade the best place for a walk. Magnolia trees, live oaks and a few palm trees line the 60-foot-wide wooded strip that extends from 4th to 20th streets along Heights. Weaving in and out of the shade is a mulch-filled path. Gazebos, a playground, a Victorian rose garden and a World War II memorial dot the 1.9-mile course. It passes some of Houston's most impressive early-20th-century architecture and is the site of frequent public art exhibits. There's consistent foot traffic from early morning to past dusk, but with so much open space, there's more than enough room for everyone — canine and human — to feel comfortable.
