I was in Vegas last month at Harrahs and they were indeed at 6-1, it also shows the opening line which was posted 10-1-11, they were 40-1 at that point. The guy working the sportsbook said the Cubs always are bet heavy, thus the low odds, but especially when Theo was hired, they got a lot of action and dropped the line to discourage betting. Ever since the Rams won the SB in 1999 at 200-1 Vegas is very touchy about futures bets.
