Good luck, Mr. Greenburg!

I admire the guy's guts! I hope you don't get into a hassle for calling it a boat.

It ain't a floaty kind of boat or a splashy one either..Well it may be splashy if he gets into some thin ice. In any case it is propelled by sail power and it goes fast.

In his blog, he reckons the warming during the day is making the ice flatter, but it looks surprisingly undulating in the photo. I would be fairly nervous about driving a car at 120 mph on a surface like that. Wonder what his suspension is like.
