Every year I drive to Louisville for the Derby. I always leave a day for caching and Of course I try to cache on my way up, to break up the monotony of driving.
Longest Hike was Eriks Invisible cache, I think it was around 4 miles. then the cache that seemed to be the longest was the Lacy's latest cache where I did the River walk! That one just seemed to go on forever!

When choosing caches in Nashville, check the description closely. Some of them to the north of the airport are on the side of cliffs along the river. We found the best opportunities in the Shelby Bottoms Greenway, near the "Don't let the snakes in!" cache. But don't approach Shelby Bottoms without a bike, or at least roller blades. Another successful area for us was near the "At the Y?" cache. "Sit a Spell" was easy.

Thanks. I'm looking at trying to get as many drivebys and whatnot as I can, as I'll only be in nashville from ~5:30 OR 6:00 until ~9:00 Eastern time. I've downloaded something like 30 caches in the area around the airport, as well as several int he murfresboro area. Any other suggestions for which caches are quick and easy? I'm trying to read through the logs at this point, but thought I'd ask around.
