At the campground where we rented our cabin, they had a Hallowe'en weekend which sadly was rather half-hearted... but I thought what a great opportunity to advertise! So the morning everyone was to decorate (only 4 campers did) I hung out our bookmarks and pamphlets and Elora's Scare Fair postcards in the trees surrounding our cabin. (String? Mom cut apart a firewood sack and we used the orange fibers!) When we came back from the beach, they were all gone!!! The managers felt it was "too distracting"... okay, then all decorations would be distracting, now, wouldn't they? Anyway, they said we could hang 2 or 3 but no more. I hope bats poop on these rather hypocritical individuals.
Anyway, on 3 nights we enjoyed bat-gazing while they swooped and dove to catch their dinners. They are just so neat to watch!
