Thousands strip for protest run
Thousands of people have stripped to their underwear and run through Salt Lake City to protest against what they called the "uptight" laws of Utah.
Undie Run organiser Nate Porter - who estimated 3,000 people took part - said the goal was to organise people frustrated by the conservative nature of state politics.
Nudity was prohibited by organisers. Participants donned bras, knickers, nightgowns, swimwear or colourful boxer shorts - and some added political messages by expressing support for causes such as gay marriage on their chests, backs or legs.
Salt Lake City is the home of the Mormon church, which is a vocal opponent of gay marriage.
