I started geocaching in 2004 and used to be quite excited about finding geocaches with trade items, Altoid tins magnetically hidden on public water fountains or around public electrical boxes, or other neat hides. But I've never really been all that active, typically fitting GC in whenever I travel.
If I'm traveling to a new State or Country, I'll seek micros, otherwise I filter them out. On the few occasions that I HAVE planned GC excursions, I've filtered the micros only to find some micros labeled as small, resulting in minor annoyance. (If you can't fit a writing stick in it, and/or it's a log-only, it's a micro. Just my opinion.)
Even though I've not been extremely active, I feel the burn-out. I've been combating that by obtaining some small trade items to plant in future cache finds. That has stirred the juices. Now if I can only find the time!
