The cache is at the posted coordinates, but you must first meet the challenge before you can log this one.
During my brief stint in Wyoming, I was able to pad my earthcache numbers for the year a bit while in the shadow of Yellowstone National Park. (Which is loaded to the gills with earthcaches!) Once I got home I found I was only three away from 50 for the year. So I went out of my way after one one of the BWTG events to pick up the last three I needed to hit this milestone. Afterwards I thought: "That might make a good challenge."
To log this cache you must have found 50 earthcaches in a calendar year.
That's pretty much it, just find 50 earthcaches between Jan 1st-Dec 31st. The finds can be anywhere. Just show that you've had a big year of earthcaches. You can choose to show you meet the requirements however you wish. Yes, previous years do count! When I ran the stats on Project-gc, there were many in Michigan that have hit this goal, and others who have come close.
The cache itself is a small, recycled container. You might remember this one. I've used it before. I used micros on this road last time, going with a little bit larger containers this time. See how it goes.
