Being a native hoosier, I know you have looked to early at the possible weather conditions. This year the only time the weatherman has been right is when they tell you about yesterday!!
Seriously, in Indy today its low 80s and pretty high humidity. The next five days they are showing dewpoints around 73 to 75, thats a WHOLE lot of moisture. The winds have calmed compared to a week ago, hopefully they stay at least constant so all of you get good flights.
A couple of us from the Plainfield Screaming Eagles will be up on Friday. If you see a short(6'5") guy wandering around without a plane thats me.
Good Luck to All
Steve
