RE: Grumman Widgeon
7 miles per gallon isn't too great but on the positive side you get 10 miles per gallon in Canada (bigger gallons). Seriously though, as you know we sell gasoline by the litre which is about equal to a US quart and our prices are pushing $1.00/litre. It makes it pretty expensive for anyone wanting to travel.
Ercoupe sounds great but I still like twins (or quads).
