UPDATE II!! 9/26/2016 -- Re-enabled as the original container was stolen. Difficulty has been increased as this new container makes it hide and blend in a little bit better.
UPDATE!! 3/26/2016 -- Hiding spot has changed a little bit (hopefully a little less conspicuous now). Increased both the Difficulty and Terrain rating; finding the cache now requires crawling in a tight space over some rocks.
Between the trolls, the jabberwockys, and samsquanches, you're likely to only see trolls here.*
You're looking for a camo'd ammo can large-ish flat lock-n-lock. At the time of hiding, it's stocked with a couple tradeable items and, for the first 6 finders, six one-riyal notes from a recent trip to the Middle East.
Since this is a Letterbox, there is of course a stamp and inkpad -- these items are NOT swag! Please don't take them!!
And feel free to add your stamp to the log book.
I bike past this area quite a bit during the summer, so this most is easily accessed by bike or on foot, but since this is hidden in mid-autumn... Parking is available across the street -- 45th Street can be pretty busy so use the crosswalk!
Please re-hide as you found it!
*Although I make no promises of what you may or may not actually see when hunting for this Letterbox.
CONGRATS to AThrilloftheHunt and TankGirrl for the FTF!!!!
And thanks to Salz69 for pointing out how woefully incorrect my original hint was.... it has since be corrected.
