I could very likely land an R22 in your back garden
I'm sure you could, and it sure would be fun to try !
You would be first candidate EVER to arrive by air ! ! LOL
The garden is quite large, not very many trees in vicinity ;
but there is a significant slope, which might just put your blood pressure up a bit . . . . . .
. . . . . . which is what this thread was all about to begin with !
