This week's Friday Morning Post is celebrating Theodore Roosevelt National Park, where rugged landscapes, diverse ecosystems, and rich history come together to create an unforgettable experience. And this week's jigsaw puzzle is inspired by some of the residents of the park—North Dakota's feral horses! Check out this puzzle and learn more about the park in the post!

Thanks, everyone, for the wonderful comments last week with your times! A number of you told me your firefly stories (and I loved them!). The fastest time last week was an impressive 5 minutes 58 seconds! On average, it took 11 minutes and 21 seconds. And, as usual, my time was one of the slowest at 17 minutes 45 seconds.
