This cache replaces my archived Little Red Caboose one. The history of this unique location is spoken of at the Caboose webpage. The Caboose container vanished once too often so I decided to make a new cache that was more of a challenge to find.
When you find the marked location you should find hidden “bait” that you’ll need to retrieve the match container (the swift). The swift is not too far directly west of the "bait" and a good 10 feet up. The trick will be to "feed” the out of sight “birdie". He’s drawn to the bait. "Feeding" him is the way to catch the little devil then you'll be able to lift him from his "nesting place". Look for a branch that’s nearly 10 feet long and tie the bait to the very end of it. A stick that has a branch at the very end or one that is curved works best. I hope you don't mind getting dirt on your hands at this point. The sticks are often muddy. I left one against the back of the chimney for the nest geocacher. To put the bird back, just get him home and yank the bait sideways.
The cache is no longer in the large interesting structure nearby so do not climb on or into it!!
I hope you have fun.
By the way, my field biology teacher back in college described the noisy little chimney swifts as cigars on wings. They never seem to stop chattering while on the fly. I especially like seeing them high in the sky right before a thunderstorm.
