I'm a newby, so maybe this is old news. I can't find anything more recent than 2018 on this topic. So, if I look at DJI's latest interactive geomap of the DC area, there are many areas within DC that seem to be subject only to an altitude limit (150m?). Before I purchase a DJI drone, I want to ensure that as long as I don't fly in restricted (red), authorization (blue), warning (yellow), or enhanced warning (orange), I can fly in DC. Appreciate any advice that people have. Thanks, Todd
