I'm with ya....I'm waiting until 3pm CST to decide. I'm in Columbia, MO which is two hours West of Tri-City. I can take the chance on what is sure to be a great event, or go to a winged race to the East of me that only has a 20% chance of rain..... I work as an aircraft mechanic and I have the weather software that my pilots us installed on my home computers. Based on that, Tri-City is actually looking pretty good, IF they keep the show moving along. Everything that is building West of the STL area should fall apart about 100 miles West of the track. BUT....This is the Missouri/Illinois area during the Spring and ANYTHING can happen, especially if the sun decides to break out.
