A FEW HIGHLIGHTS... The bus tours, which cover a wide array of the valley's architectural gems, are always bustling. The vintage car show, too, will attract a number of attendees on Feb. 18 (and it is free to boot). And, yep, there's a trailer show, too, where a number of retro beauties go on display. (You'll probably want a nickel for every time you hear someone say "I want one of these in my backyard.") Home tours, fashion shows, and cocktail parties are also on the schedule. Only piece of advice? It's a big schedule, so it is worth landing on three or four must-attends before making for the P.S. And you'll want to remember your Mad-Men-esque outfit, too, complete with starburst brooch. Make sure it is of light fabric, though; Palm Springs is pretty perfect even in February.
