There are various geophysical techniques that can be used, such as microgravity measurement, ground penetrating radar, etc. They cost some money and require someone with some experience to use.
I saw the most impressive talk at our recent convention about the exact same sort of situation here in Virginia. In that case there was a small hole on the surface that blew a lot of air (if you have this ignore my first sentence). The amount of excavation was HUGE! But the cavers persevered and a cave was found.
On the one hand, a person could argue that it's not worth the effort. On the other hand, it might be VERY useful to know where you cave is so you don't, for instance, park your car above a cave that suddenly collapses one day.
Not to mention, it would be super cool to have your very own cave.
