Mammoth one-day trip NYE

Dani (a female meetup member) and I are going to Mammoth for one day, 12/31. We are doing this as cheap as possible and we have two spots open for this trip. Here is our plan: We leave SD around 2:30AM on the 31st. We get to Mammoth around 9:30AM. We snowboard 9:30AM-4:30PMish. We check into hotel (cheap hotel; already reserved-we have one room with 2 queen beds for $150 for one night). We'd either go out or stay in the room for midnight; we'll find something fun to do, just not sure what that is yet. We sleep; we check out on the 1st and drive home. We will split all gas and hotel costs. We'll take my Honda Civic which can fit 4 people (and has racks). Please be prepared to help drive (make sure your car insurance covers you under other people's cars.) If there's enough interest, then we'll get a 2nd room and a 2nd car. Both males and females are welcome. If you're a male, please be OK with sleeping with another male or on the floor. Most females (including myself) won't sleep with a male (unless it's their boyfriend). Email me asap if you're interested or if you have any questions. Thanks! Becky Bardwell 858-926-8043
