So today I went to an area outside of Las Vegas (about 15 miles) where I have flown multiple times and all of a sudden a big blue no fly zone circle enveloped the entire county. Never seen anything like it. I went on this forum (and others) and figured out how to unlock the no-fly zone restriction. However, the notes indicate that the restriction will not be lifted until Friday, February 21. I know DJI does this periodically when special events occur. Would they do this because the Democratic Debates are here tonight??
