[making a signature item]

A nice thing I've seen is small pens (@3") with a cap and a chain with your handle engraved on them. They make great SWAG.

[how often are caches removed?]

I have not had good luck finding caches. I'm pretty sure I am in the right location but can't actually find many of the caches (I'm 2 for 9). My question is: Are they actually there any more or have they been accidentially found and taken by Muggles or what? Does this happen and how often and what do you do if you suspect this has happened? The ones I've been searching for have been in high traffic areas and might be susceptable. It makes me question if I should look harder or even be looking at all.
