Good morning from Texas, y'all. I'm planning a solo road trip to caves in Kentucky and possibly some in Tennessee. I'm looking for any information on caves that are NOT as well known as Mammoth, etc. (In other words, I'm not fond of standing in long lines with screaming children!) I'm going the second week in September - after said children are in school. Any advice on other natural attractions would be appreciated. I'm an experienced roadtripper but this is the first time I've used RTA! I turned to this source as I have limited time to plan this trip. Thanks for your help.
