While it might be mid-May, it still gets a little chilly in Los Angeles at night. In an effort to help those stranded without a sweater and sell a few ponchos, the L.A.-based poncho company Señor Tyrone just launched a "Poncho Express" program that promises local delivery of one of its fine, made-in-the-Andes ponchos in under an hour with only a simple tweet. To get your hands on an emergency poncho, all you have to do is send a tweet to @senortyrone bearing the hashtag #ponchoexpress with your location. Delivery is free, and the messengers accept cash and credit. And the good news for cold folks in New York is that a similar service is planned for a fall launch. 

Before you get stuck poncho-less out in the cold, head to Señor Tyrone to see if you're in the delivery zone.
