Ive seen two different dangerous items in caches that I dont care for as i occasionally cache with my kids. Lighters don't belong in caches...especially those that I thought were supposed to be illegal to sell in Maine because they look like toys. (I must be wrong on this actually becoming law as I've seen all sorts of lighters at places like Walmart and Reny's that look like little fishing poles recently out with the grills and BBQ supplies.
