If you are looking to blow a few minutes or an hour in Lehi, Cabelas will deliver.
There is a good size aquarium with local fish from Utah, a small one room museum of taxidermy at its finest, a one room gun museum and a mountain covered in stuffed wildlife of all kinds.
Great for getting an up close look at wildlife.
Then up stairs they have tents set up so the kids can run wild and pretend they are camping while mom and dad test out the camping chairs.
There is even a river with fish that you can feed for a quarter!
All without any mosqitos or dirt. Best part, it's Free! You can just walk around and not even buy anything if you don't want too.
