Thanks to Planetary Pursuit, lots of people have even more souvenirs. This cache gives you something to do with them. This is a Challenge cache. You must have met the simple requirement of obtaining 70 souvenirs since you started geocaching. Do not claim a find until you meet the qualification requirement.
The cache difficulty is based on the challenge rather than the difficulty of locating the cache.
At the time I placed this cache, I had earned 82 souvenirs.
