just remember that 100 miles isint far for the herd to travel but the year i went during thanksgiving they were much closer than that and didnt move much closer in 4 days because the rivers and reseviors didnt freeze over. i know they can certainly swim these lakes but for some reason that year they didnt want to. im sure every year is different but i would stay on top of the latest info. if it were me at current gas prices i would keep an eye on things. i dont think you have to panic but if its definatley not looking good for next week i would maybe try to move the dates but im sure things will work out. i got screwed once and i hope everyone scores a big bull without getting a line of BULL. you first week guys keep us informed when you get back. id love to go this year but im looking at next year maybe.
