FLAT TIRE! :[

So today Thomas, Jamie, and I went to Spanish Fork to hang out with Mark, Laurin, and Emma. After we got there, Jai and I left their house to go to Little Caeser's to pick up a pizza and on the way back we all of a sudden heard a really LOUD noise and then lots of air. Gahhhh. So we pulled over and, sure enough, a super flat tire. We really don't even have any idea what happened. It's not a nail...it's a GASH. And there was nothing in the road. And the hubcap fell off and flew across the road. We're wondering if the hubcap fell off then gashed the tire...can that even happen? I don't know but something happened. So we called Tom and Mark and they came and replaced the tire with the spare. Thanks, guys! :]
