I started geocaching roughly a month ago and it's really fun activity to get into.
I had a few questions (though one was answered already here > What should be carried in a standard Geocaching bag?) but my main question is typically for the UK due to people nature here, though all ideas are welcome.
So far we've a small geocaching kit consisting of pens, extra paper and lunch bag style plastic bags to help protect damp logbooks (of which thus far we have found many). Sometimes we pick up a few small items that we add in - so far we haven't taken any items out of a cache - these were mostly small toys, coins, etc. This is commonly what we find in caches as well.
Most caches we find currently are small (excluding micro) with the odd regular. And per item we would look to pay £3 or less, as we can find 6-7 caches per day out, but price does not necessarily constitute value to an outdoorsman. I would reserve pricier items for harder caches (4-5) but we are currently only finding 1-3 rated caches.
I am loathe to leave things like matches or fire starters or other useful outdoor tools such as that due to idiots who might abuse them. Though once or twice I've seen a compass in the caches and think these are a good idea. Caches should be, I believe, useful outdoors items, but to avoid caches being filled with toys and money, and wanting to overall improve the quality of my local caches:
What are considered good items to leave in a geocache? What items should be avoided?
