Everyone writes off Nebraska Avenue as a dangerous road going through bad neighborhoods, but occasionally I'll bike along Nebraska -- like this afternoon, for example -- and I've never had a problem. In fact, I'm fascinated by the businesses, which have equally fascinating signs.
No one said the business owners were experts with punctuation. Doesn't everyone confuse an apostrophe with a comma?
