Penni McDaniel posted a good post "I really do not understand how a festival website could not post the address of their festival. It just blows my mind. Providing the name of the park or venue is not enough."
Let's say this was an oversight and of course the festival wanted to have the address on the website. But, the person helping with the website was not around to help them. Websites can be a pain for a lot of us at times and they're not cheap to keep up.
My thought was to make a database that is free to everyone, it needs a simple interface and maybe a heatmap. This would be for both the fans and the artists. I'm very uneducated in this space, and, we would need help from others to help make something that fans and artists would use.
I just made a quick database and some of the information might not be right. This will give you an idea of what I'm talking about.
Festivals & Jams Database

This is what you would see by search

This is what you would see when searching TN

This is what you will see when you lick on one of the Festivals.
Is this something we need in our Bluegrass Community?
