Geocachers put stuff in parks and forests, under bridges, in dusty books, etc all the time. Considerations... - Timescale... physical works get built replaced and blown up, materials degrade due to environment, forests burn and cut, map and key holders die or turn sides, etc - Human presence... Cops, tattletales, tails, lookers on, metal and density treasure hunters, building remodels, etc - Tech... SatNav can be turned off, EMP happens, magnetic poles move, star fix inaccurate, etc Geocache gamers and time capsulers often bury PVC pipe with photographic map of path taken from insertion point to cache. Simple often best.
