While I was visiting a friend in Adelaide for a week in Jan '70, I bought my husband 1! It was red & white. We have many trees in our yard, but it was never hung up, & is still wrapped up, in the spare-room, somewhere! The backyard is rather uneven, with no grass to fall onto, only leaves & a few stones & rocks, under the leaves! I'd also be worried about bird poo falling on us, but I'd love to be lying on it, with a book, or my laptop!
