I like to add things ad hoc just before I purchase them.

That makes it easier to justify impulsive decisions like flying to New York on three days notice to take a girl to a Billy Joel concert at the Garden. Or to buy a $200 ticket for Elton John next week. I've definitely always wanted to see Sir Elton at a glamorous venue like US Bank Arena. Better add those to the list so I can cross them off while there's still time.

One of these days, I'll finally see Van in concert. I almost did that the week after Billy Joel, but ended up having a conflict.

I also check out Red Rocks every once in awhile to see if anyone is worth playing to head out there.
