First to Did Not Find - there's no certificate for that, but I was the first to post a DNF on a cache that, today, I was convinced I would be the FTF. The e-mail came in just after lunch and I had a lunch break followed by a prep period. Now, normally I stick around and get some stuff done, but the timing was just too perfect for this.
I'm not going to be all dramatic about it, because there was no drama. I arrived. I searched. Looked up, down, around, over, under, in, below, beside, above... nothing; at least there was nothing that I could see. I'm sure the cache is there, it just eluded me today, and I only had about 30 minutes good searching time before I had to zip back to school to do a lesson on erosion, groundwater, and just generally how water interacts with the world.
At least I was successful in THAT

Students seemed to enjoy the simulation and we have a video of it for further analysis.
Oh well... in the summer I'll have more flexibility to chase after those FTF's. Would be nice to have at least one.
