These things are really hard to pull off, everyone always likes the idea of it and knows they would enjoy themselves once they get there, but when it comes time to cough up the time & money to make it happen, they usually fizzle out.
Sometimes things just happen too...in my case, I had some issues with my truck engine back in May, decided to replace it (due to high mileage) even though fixable and the replacement engine sits to this day on the floor of the garage, the truck hasn't moved since May. Really busy with other stuff at the moment. Showing up at the meet with a rental car & no PC just wouldn't be the same.
