You have to sign up, but there's a free membership level. They expect Supercharger to foal today for sure. She's hanging out right now, some pacing, and we should see a new sibling to Super Saver on the foaling stall camera by tonight. Always fun to watch the babies being born.
ETA: Okay, can't tell if the one that was up before is still (or was ever) available for free. Might only be able to see her if you pay in. Sorry. I had to reboot and when I went back, the camera I'd been watching said it wasn't free, but I know I'd had it up earlier. Oh well.
