I'm not sure how congested it is but the Farm Progress Show is now located just east of Boone on HWY 30 and it is going on this week. I heard on the radio yesterday that there was some traffic congestion due to the show. I know it gets a lot of visitors and I would guess people will be leaving there about the same time people are trying to come to Ames so this is just to give people a heads-up about that.
