Atlanta supporters of the Human Rights Campaign got their groove on Saturday, channeling the 1970s for the group's annual bowling for equality event. 

"That '70s Bowl" featured big wigs, bell bottoms and shades as it raised funds and awareness ahead of the 30th Annual Atlanta Gala Dinner & Auction on April 22. The annual event at Midtown Bowl favors its themes, including Superhero Bowl in 2016, bowties in 2015, Rock N Bowled in 2014 and Peach Bowl in 2013.
