A very helpful person at IBU sent me the information on the licenses. It is very interesting. I am not sure if a moderator wants to pull all of the venue/licensing talk into another thread, but I will leave that up to smarter people than myself.
A license is for 6 years, but can be pulled at any time by the IBU.
There are currently 23 venues that have a Class A license with 4 in what is called "prolongation" There are currently 21 venues with a Class B license with 5 in the process of prolongation. Some names are familiar, others are not.
There will be public documents that will come out within the next month or so, but let me say I was surprised by some of the names on the list. The IBU has has that I not share the names until the public documents come out, sorry. But if you asked me questions, I might be able to answer them.
