It was 8 seasons ago, but I set mine up in January on the first workday of the year to get my spot so I can't help you on walk-ins, but I can say there was only 1 spot available in ours and nobody showed to snatch it up.
How old are you? Already have a bucket list? My bucket list is just enjoying everyday I can and making the most out of it. I do what I do whenever it happens. To answer correctly though mine is to watch my boys succeed in life and have it better than I do. That would make me happy/complete.
You're not setting up a list to rob people are you? j/k BUT, Lots of people never share their arsenal for reasons because of this. Gun robbery is big, I know many who have had their house broken into when they're gone and all their weapons stolen.
I've seen and ridden with, as about 40 others have from this site, 2 sportbikes near the 80-100k price. They're rare and works of art, but those are my answer.
