How do you have a tide guage on an overhead wire?

Well, this can be a problem. However, I've traveled the entire East Coast of the US and I
only remember one overhead that made me nervous - in Pine Island Sound, FL going to Sanibel. Its listed as 80 feet, but sure looked like it was sagging a bit! However, the differences between MHW and highest astronomical tide are maybe 3 or 4 feet in a worst case. I've gone under bridges with 3 or 4 feet of clearance - a few times only a few inches - but I wouldn't go under a powerline with that little clearance! "The_navigator©" wrote in message ...
