glockgal, you wanted to know a little bit about the Othello Tunnels.
I've posted a handful of pictures I took on the weekend on my 21 freckles blog if you'd like to take a look at them.
Or wait until you're there and see them for the first time with your own eyes. :o)

(if you go look, click on the images to see bigger versions of them) *muah*

Have a great time!!!
