Well, we survived the worst one-day performance in the stock market since 9/11, although the editorial board will be monitoring the news from Wall Street again today and working on a weekend editorial that looks at the critical balance between sufficient regulation and marketplace freedom to innovate. More on that later. We heard from readers on the Target Field naming rights issue yesterday and plan to publish an editorial on that topic tomorrow or Thursday. Meanwhile, we're also interested in your thoughts on ATVs in light of the Star Tribune's "Renegade Riders'' series. We see two key issues and would welcome your comments: Should penalties for illegal use of ATVs be strengthened? And is Minnesota asking for more trouble with its plan to dramatically expand the ATV trail system in the state?
