Everyone loves to get high. And thanks to transport authority Metro, sightseeing helos are flying the St. Louis skyscape again after a long hiatus following the 1993 flood. What better way to introduce Loucomers to our many marvels than with a 135-mile-per-hour scream at 600 feet above sea level? Gateway Air Tours, an outfit out of Long Beach, California, dispatches two pilots to St. Louis for the five-month flying season (Memorial Day through October). Visitors can travel in twos or threes and choose from two-, five- and fifteen-minute narrated rides ($23, $43 and $99 per person, respectively). Numerous photo ops abound as the Robinson R44 helicopters (with panoramic windows) pass over sights including Anheuser-Busch and the Lemp Mansion to the south, Tower Grove Park and Forest Park to the west, and the City Museum and Chain of Rocks Bridge to the north. Reservations not taken; simply show up at the barge beneath the Arch between 11 a.m. and sunset to go up, up and away.
