I personally thought the race was good!! I felt bad with all the rain and assumed turnout would be trash there.... But on TV it didn't look bad! I think the rain added nice drama, and the product overall was really good! I'd hope for a second race in Chicago.
I personally found my self at one point watching SVG's onboard feed on YouTube and thought to myself, "Damn! It's pretty damn cool seeing the skyline right there through the whole race"
I think your thinking of a different event, but as a NH resident, I personally am OK with the fact that they waited it out.
