That's brilliant. My pal cycled from Cambridge to Mildenhall, about 30 miles each way on a student bicycle, to see an SR71 around 1979/80.
I was almost asked to leave The Smithsonian for trying to lick their SR71, Ms.T dragged me away. One of my favourite aircraft.
That's actually genius... when you're finished with the BBQ, the ice will have melted... flush and dampen the coals.
