The best thing I have found ever was a complete set of golf clubs. I was on vacation on Prince Edward Island and was coming back to the campsite after visiting the nearby bakery ( 15 miles away) for bag of scones. I was passing a potato field, and saw a gleam coming from a deep clover-covered ditch on my side of the road. I stopped the bike and uncovered a complete set of golf clubs with the golf bag as well. it must have fallen off a vehicle sometime. I was wet, but not badly rusted. I put the whole thing on my back and pedaled back to the campsite.
I found a $20 bill yesterday coming back from a 31 mile Tour De Cure bike ride in Bar Harbor, ME. It was blowing across the road when I was at a stop light heading home. I ran out of the car and pocketed it.
