100 rounds is a good number. It'll be easier to shoot more if we want than to figure out what to skip if we're moving slow.
I don't have any clean IDPA/IPSC targets left, but I've got a ton of cardboard saved up for target backers, and 2 stands I can bring.
I can also run off targets at work (ssshhh) if they fit on a 8.5x11, 8.5x14, or 11x17 size (I use the .pdf's from Todd's site a lot).
