This is so much fun if you are the kind of person who has garden visitors - beyond family members. The hard part is finding one of the old rotary dial phones. (You can use anyting, but these somehow seem best). Locate the phone where guests are going to see it ...and naturally, they ARE going to ask ..."Why do you have a phone in the garden?" ...and at that point, you just slyly grin and answer "In case Mother Nature calls!"
