Yes, you are more than welcome to attend any event as ALL MINIS are welcome.
We are a standalone event run as a independent group of MINI enthusiasts who enjoy our cars and are staging this annual event. As we are not a club, we therefore do not ask for any subscription fees.
Short answer is that not being a club or business, means that we have no funding nor bankrolling for any event. So a few well run and respected businesses, involved with the MINI scene, donate to help us bring this annual event to you all.
