On 4th July week 2015, I was planning to capture some fireworks shots. I went to Civic Center park Denver on 3rd July to take some shots but couldn't get a spot from where I could take a nice shot without any obstacles so next day I was shortlisting some places and heard that city of Black Hawk has a firework show which lasts almost 30 mins and I will have sufficient time to adjust my shots so was there on the roof top of one of the casinos and witness an awesome firework show. The first shot below is of Civic Center park and all others are Black Hawk. Regardless of you like the pictures or not, I would recommend visiting Black Hawk for a superb 4th July fireworks, which I think is one of the best in the country.
