I have no problems with the lineup, though I wish Killswitch Engage performed more toward the middle of the lineup. A bonus was that I never saw Bush or Alice in Chains before, and they did a good job. Several cover songs were played by different bands throughout the concert, and I was happy with that.
I disagree with the stages being so far apart, as I had to keep moving back and forth to get a good look at the performing band. If you're into the band playing, you shouldn't be distracted by stage setup on the other stage.
I wish there were more opportunities to sit down between sets so my legs aren't so tired during the last few sets. I prefer Boone over Indianola since the Central Iowa Expo, though a little muddy, didn't destroy people's shoes unlike two years ago.
Although I didn't mind Friday over Sunday, perhaps Saturday would please the most fans. At least on Friday or Saturday (over Sunday), I don't have to worry about going to work the next day.
Fans should be let in at least a half hour before the first band begins its set, because this time most people were still in line or going through security while Fatal Addiction was playing.
