It's officially winter, and you can feel the cold down to your bones as you jump over rain puddles and scramble to stay warm in scarves and sweaters and coats. Guess what? We've got the remedy: you can win an all-inclusive three-night stay in gorgeous, sunny Puerto Vallarta, Mexico at the CasaMagna Marriott and a zip line tour, all courtesy of Virgin America. This includes two complete round trip flights (blackout dates apply). Talk about a vacation!

And of course, thanks to Virgin America's excellent in-flight amenities, relaxation starts even before takeoff. Once you step onto the aircraft and settle into your luxurious leather seat, soak in the mood lighting and wi-fi, order handmade cocktails, food, and movies you wanted to see in theaters but never did, you can pretty much forget that you're on a plane to begin with.

Here's what you have to do to win: sign up for our newsletter, which is a bevvy of the best insider info on food, drink, culture, events, music, tech, and travel in and around San Francisco. You'll instantly become eligible to win this tropical getaway. Trust us, you'll be talking about this trip until it gets warm again in San Francisco.
