Ah, Alan, you remind me of the man on the beach who finds a bottle, and is cleaning it off when - shazam - a genie appears and offers to grant one wish (times are hard, even wishes are getting devalued). After thinking a bit, the man says, "What I've always wanted is to go to Hawaii, but I'm terrified of air travel, and I get dreadfully seasick on even a canal. Could you build a causeway so I could drive there?"
This sets the genie back a bit. "I'm not sure we have the technology to do that," he says. "We couldn't float the whole thing, and concrete pillars to the ocean bottom, that's a prohibitive amount of cement...Is there anything else you want?"
The man contemplates this for a moment. "Yes,, there is," he says," I've always wanted to be able to understand women, you know what they're thinking and..."
The genie interrupts him. "Two lanes or four?"

On the other hand, if Joe could find the information on the internet, he probably could provide the answer.
Blessings,
Barbara
