Gosh... almost forgot about this thread. Thanks for finding it, Frigg. (Love your Avatar, btw)

Here's a recent 'great find':

Glo-in-the-Dark Rope
Ebay Seller ' bugluver72' - [link to shop.ebay.com]

100 feet of 1/8" inch Nylon Glow Rope, or get a size cut to length. This stuff has a tensile strength of 1,000 pounds, and… it glows in the dark! How many times have you tripped over your tent ropes, or walked into the washline at night. We've got this in our bugout bags for multi-use: camping, path-marking, to make kids feel secure at night, etc. It's on the pricey side, but very nice to have when you need it.
$40 for 100'
