The summer heat demands that you keep the kids inside, hour after pent-up hour, day after frustrating day. Don't throw yourself under the wheels of a train. Just throw yourself near the train -- in this pretty park with a restored historic train depot, an antique carousel and a clock tower. On Saturday evenings in May, June and July, the City of Scottsdale sponsors a summer concert series at this oasis. You can bring your picnic basket and spacious blanket and mercifully decompress with others of your age group while the little ones run freely and safely in the park's wide-open spaces.
