I am just curious- we went on our first hunt today, looking for a theme cache. As it was a hippie theme, we brought along some incense which I enclosed in a ziplock snack bag. Sadly, we didnt find it but I was just reading on another thread about not trading items with scents due to animals. Would using baggies negate that? When I bagged them up, I was only thinking of keeping them dry- I didn't take into consideration animals.
