I'm a little perplexed as to why someone was riding an ATV on a runway in thew first place. Seems like they should have not been there, and were possibly violating some FAA rule/law. Wonder if the FAA will go after them, or at least send the appropriate law enforcement branch after them for action. What the pilot did may not have been smart, but he may have been trying to land and saw them on the runway at the last moment.
