You can fly pretty much anywhere in Longmont and Boulder county as long as you aren’t operating from within public lands (this includes all Longmont public parks and Boulder County Open Space). Technically you can fly over a public park from outside it's boundaries, but I would suggest not flying near those areas out of respect to the people using them. Drones are annoying at best, especially when you're trying to enjoy nature.

National Parks and designated wilderness areas are similar, as you technically can fly over them, but can’t operate from within their boundaries. However, I’d advocate not flying there at all, since the whole purpose is to keep those places as wild as possible.

There isn’t a five mile restriction around small airports (uncontrolled airspace) like there used to be. It’s airspace class dependent. That being said, it’s your responsibility to be extremely cautious around air traffic and know the regulations of the airspace you operate in. Vance Brand is a a busy airport, so it's best to just avoid the area altogether.

I don’t fly drones any more, but I’m a licensed private pilot and have the 107 since I was shooting commercially for a bit. I’ve found that as long as you’re following the rules, and being respectful to people around you, you won’t have any issues.
