We placed our first hidden cache after about 2 weeks of caching and 12 or so caches found.
I'm hoping to place my 1st multi cache soon and have ideas for a puzzle cache.
We take placing of caches seriously and make regular visits to the 2 existing sites. Whilst we did wish to get a few finds under our belt for experience, we may have lost interest if we had to clock up a minimum number of finds before hiding a cache.
You are always going to get someone who doesnt play the game as it was intended, some people hog travel bugs, some lose them, some dont re-hid caches very well, some people (I've read in forums) even log first to finds without signing the log book!
Its a pity that some cache owners may end up giving the sport a bad name when their unattended caches end up as junk but unfortunetly this may well happen with more experienced cachers as well as the inexperienced.
