I love them both! The idea of mixing them speaks to me. I really like the idea of walking along a trimmed and tamed path only to find a plastic flamenco or two posed among the flowers!
Another somewhat whimsical idea I like is using sheep for lawnmowers. I dream of a green expanse dotted with wooly creatures keeping the place neat (and fertilizing it a bit along the way
) I wouldn't mind a pony for on-site transportation too. I might use a halter or bridle for him/her, but the only other thing I would strap on might be a unicorn horn!
Maybe one day.
