I did t a couple years ago. It was ok, nothing spectacular. I prefer to be very close to the fireworks. Very loud, and ash falling on you.
Not gonna happen in Colorado these days. Almost all the fireworks have been cancelled. Even many of the firework stands have admitted it's not a good idea and are closed. I'm planning on watching the NYC, DC & Boston shows on TV. That's about all the fireworks anyone will see on Colorado.
Unless, of course, you're interested in flying near (not over - TFRs you know) the many fires in the state. And Arizona. And New Mexico. And Wyoming.
