Stop in the eastbound or westbound Blue Earth rest area on I-90 and spend some time looking for this cache.
This cache is hidden in a cheap plastic food container measuring about 7 by 7 by 2 inches [edit - October 2022 - this is now a large mayo/peanut butter jar]. It is about a 5 minute walk from the west-bound rest area to the cache and about a 10 minute walk from the east-bound rest area. There are nature trails accessible from the eastbound rest area, but the cache is not hidden there.
The cache contains a pencil and a logbook. On May 22 2004, We replaced the cache (somehow it had been lost...) verified it's position.
If you are on a cross-country trip, take a break and find the cache!

If you need a place to camp overnight, the Faribault County fairgrounds located just south of the freeway has inexpensive camping. Full hookups are available in a gravel parking area, and some tent sites are available in a shady grassy area. Very nice bathrooms and showers are available to both camping areas. If you're coming off I-90 turn right at Bomgaars, and watch for the entrance to the fairground area on the left.
