Re: Fly Fishing Film Tour...Chicago show!
Even though I'm in Australia it looks like you might have to go for a larger venue as 180 seats is very small that would fill up in 10 minutes in our area of around 14000 people even though there are heaps of people who don't fish they are always interested.
I imagine in Chicago,going on your Ann Arbor Tour,you could run it nightly for a week easily,then many people would still miss out.
Have you thought of selling a DVD after your Tours are complete with access for a feedback,which would net you a few more Dollars & the people who missed out could get to see it,as well as donate????
