Actually we chalk it up to honesty and helpfulness on the part of the anonymous Juneau residents.

Like another incident years ago. A book that had been long missing was returned to the library I worked in at the time. It was one of those "Europe on a dollar a day" things. A note was included in German, which when translated turned out to be from a Swiss motorist who had picked up an American student hitchhiker. The book was left in his car, and he mailed it back to us at his expense (postage was more than the value of the paperback book, probably.)
