"One day we came home from some errands to find a grocery sack of [zucchini] hanging on our mailbox. The perpetrator, of course, was nowhere in sight ... Garrison Keillor says July is the only time of year when country people lock our cars in the church parking lot, so people won't put squash on the front seat. I used to think that was a joke ... It's a relaxed atmosphere in our little town, plus our neighbors keep an eye out and will, if asked, tell us the make and model of every vehicle that ever enters the lane to our farm. So the family was a bit surprised when I started double-checking the security of doors and gates any time we all were about to leave the premises. "Do I have to explain the obvious?" I asked impatiently. "Somebody might break in and put zucchini in our house."
