That really sucks you guys, and I feel really sorry for you. Our district has been rather quiet on everything, they aren't cancelling any trips, out of the country or inside the country. Actually, I just got back from a trip to Chicago (unfortunately we didn't get to visit FIRST

) I just figure that as long as the district doesn't say anything, we aren't saying anything to them. Granted, the district really doesn't know we exist, and I have never seen an administrator even look at our robot (except for an assembly when we got to pick up a ball with last year's bot).
Anyway, I hope you can find a way to make it, even if it means going on your own. And remember, if your parents call you in for "personal reasons" the district has to honor that as excused. At least, our does...
