After observing them for awhile, we got the bikes off the back of the van (last year we bought a bike rack, and it's been useful several times). Our plan was to bike the loop part of the auto tour, which we estimated to be about 9 miles (we couldn't find the actual distance anywhere, and it certainly felt longer, so perhaps when they say 12-mile auto tour that is just the gravel loop and not the part before it).
Great blue heron
Shark Valley down in the Everglades, with the flatness (although the background mountains sure were different!), amazing birds, and plenty of water. We teased Desert Boy to be on the lookout for alligators.
We eventually made it back to the van, happy to escape the insects. It was getting late, so we headed to downtown Brigham City to find some food. The downtown has a large sign stretching across main street that says "Welcome to Brigham, Gateway to the World's Greatest Wild Bird Refuge." I had been reading Refuge by Terry Tempest Williams, which had made me appreciate the bird refuge more. She also had some interesting information in the book about Brigham City, which started off as a communal living effort.
After dinner, it was time for a late night swim at our hotel pool. The kids improve so much each time we get to a pool. I was a little pool rat when I was a kid, so I'm hoping they can learn how to swim well.
So, in closing, I'd recommend a trip to the Bear River Migratory Bird Refuge if you like birds and getting away from the city. The bike loop is great IF you have insect repellent. Otherwise, it might be better to do it in a vehicle! The kids liked trying to find different types of birds (by colors, activities, sizes). They also liked seeing the skunk, muskrats, and enormous (gross) carp by some of the water structures. Some of them weighed more than the kids. All in all, it was quite enjoyable.
