You're right, that was a little harsh. Sorry, bort.
I guess if I actually knew the answer AND read this thread, I'd think that I had a pretty good shot at winning the damn thing if I spent some time to find the other 19 myself, rather than giving it to someone else to win.
But now that I think about it, if I DID know the answer, then I'd know them all (since I have the other 19). So, I probably would give the last one to you, so you could win the Strung Out On U2 second prize.
Alas, I don't, so I took a guess days ago. I figure if nobody gets all 20, at least I have a shot at being one of the first with 19.
But I was serious when I said you've got more than 3 weeks left, so keep looking!
