Yeah, vacations just get in the way of lifting........you gotta have priorities my man. lol.
On the real though, you should be able to work out wherever you're going. I always pay for a day or week pass whenever I go somewhere. If you start now, Thanksgiving will be the "prime" part of your cycle and you don't wanna by slacking off during that time. Either postponse or cancel the vacation or wait until you get back. Later.
