  To start welcome to all the new members of this blog. You'd better write some good stuff here (just kidding). This information may be useful to Roman and all those who are intersted. We are not going to the states for the New Year (or at least most of us). We are partying in Montreal, and probably going skiing the week-end after the New Year's Eve to Laurentides.
So Roma, it would be nice to see you there if you can make it. If anyone is interested, post your concern about it and we will evaluate your application. I'll post more precise information later, unless somebody does it before me. So I hope you guys are all finished soon with your exams. P.S. I totally agree with the mathematical proof given below.
