Please don't. Every time the cache gets opened, the silica gel is exposed to untold amounts of water vapour in the air and it quickly becomes saturated. Then it's just more garbage in the cache. Eventually these packets can tear open and the gel creates a mess in the cache.
A good point, scratch the silica... thanks!
+1 on those pesky packets that rot out our ammo cans.
No offense, but I'd like to add candles to that list of "please don'ts", especially if scented.
Bears love caches that have smells to 'em.
Working for the World's most popular crayon manufacturer, you'd think crayons would be awesome.
- Well, they're not, as all the melted wax carp left on the bottom of many caches attest.
We did a lot of apologizing when we started (and replaced a lotta containers too).
Would anybody use a chap stick that they found in a cache?
Noted: we will leave the candels at home (We don't have Bears in downtown Indianapolis, but perhaps a dog would be attracted to the smell.)
We will also leave the Chapstick at home. (They are brand new in a package and then individually wrapped, it's the potential for melting that won your argument.
