With great appreciation for J5 Crew's 100+ cache creations on beautiful Mount Tam, I thought I'd add one of my own idiom caches. (And thanks also to him for suggesting the background image when I checked to make sure he wasn't about to use my chosen title.)
The idiom "draw a bead on" came from taking aim using the "bead" or sight on a gun, but has come to be used figuratively to mean to focus one's attention on so as to understand or deal with something. Example: "Once I draw a bead on the final location of this multi cache, I'll head on over and sign myself in!"
As this is a multi cache, the first stage has no log to sign or trade items. What you find in stage one is there to lead you to stage two, and you only need one gamepiece to solve for the final coords. The others are there just in case something breaks. Please don't add or remove anything at stage one and also please be gentle extracting stage two.
