Wow, I am so going on this walk. I've done a couple of trials (made it all the way to Jupiter on my way back from Dairy Queen to work this afternoon [img]/phpBB/images/smiles/icon_wink.gif[/img]) but would love to take my little sisters on the whole thing some Saturday. We've got a long straight street right near our house which would be perfect for this--it goes down a hill, but I think it's a kilometer long so we wouldn't have to double back.

Astounding distances, especially when you consider the size of the planets, even Jupiter. WOW!!
