READERS' PICK: If you don't know how to do it, Rufus Thomas can show you how to walk the dog. Or you might just decide to take your canine and frolic at Reid Park. Reid Park has it all: a dog park converted from a baseball field opposite the entrance to the zoo, a rose garden, a duck pond, playable baseball fields, picnic areas, grills, a sports and recreation complex, a football field, horseshoe pits, a skate park and ramadas so that you and your mutt can retreat from the Arizona sun. Add to that the lowriders that strut their stuff on Sunday afternoons and even the most conservative huckleberry hound will give up a bow wow wow yippy yo yippy yea!
