I imagined that the owner would think I was nuts when I knocked on the door and asked permission to roll my bike onto his lawn, but he was totally cool about it.
The original rules (I know, I know...) call for a new tag after, what, three days? I prefer our method - gives more time. Anyway, I'm happy to go with boggy's suggestion - it's so vague and interpretive that just about anybody should be able to do it.
In my town, there's a statue of the poet Edna St. Vincent Millay, who is considered by some to be a national hero - of poetry! Ok by me, but I won't be submitting a photo of her with my bike!
