What is the JASMER Grid?

Fair, enough.  I've been babbling about it for a year now, and I was asked to define it.

The JASMER grid is your Finds by Hidden Month grid (easily accessible via project-gc.com or by using a GSAK macro).  The challenge is to find at least 1 cache hidden in each month since geocaching started. This will get harder and harder as older caches are being archived.

In the last year, we grabbed our May, July & August, and September 2000 caches. On our recent Georgia adventure, we found our June and December 2000 caches!  Just two more to go and both of them are in nearby Indiana!  I feel a Fall road trip coming on!
