Book 61 of the Boxcar Children. The Aldens are off to Yellowstone for a vacation and another mystery. Strange things keep happening and unfriendly people. Why won’t anyone talk about the lost shack in the woods along with the bag of gold. Looks like yet another mystery that the Alden kids will have to solve, if they can keep from being eaten by bears. This was a fun one but nothing terribly cleaver sticks out. If you’ve read this far, you’ll enjoy this one.
