This is very odd indeed. I have been thinking the same thing for some time now. I just got nagged about a travel bug that's been wasting away in "my hands" for a coupla weeks now. The reason is, travel bugs DON'T FIT IN MAG KEY HOLDERS! And we haven't had a decent cache listed in weeks...
Seems that our locals spit out a micro every time they pass a cemetery or village square war memorial gazebo... and if I can't nab an FTF, I just fugettaboutit... but they are cloggin up my list.... while travel bugs languish in the malaise...
Please, people - QUALITY not QUANTITY!
But, I have noticed, that creative caches seem to give approvers fits....
