Well,  what a cool city this was.  We spent five days here and have loads to say about this place.
We started out by caving at Diamond Caverns and ending up caving and camping at Mammoth Cave.

The Mammoth Cave campground is awesome, but DO NOT camp in the sites adjacent to the bath rooms.
We camped in site 12 and it was next to a bathroom and the light and noise was worse than expected.
The motion flood-lights are really bright and they ruin the camping experience.
We did not visit all 7 caves in the Bowling-Green area, but the two we checked out were the best we think.

We hit the Beech Bend amusement park in the middle along with quite a few other local stops.
The Kentucky Rumber is the bomb-diggitty and so was the tiltin-whirl!
Hand-breaded corn dogs and pretzels are hard to beat.

This city is really cool and has tons for us kids to do that does not cost an arm and a leg.

There are tons of local parks that are free and very kid friendly.
