SALT LAKE CITY (AP) — A roving courtroom has pulled up to a counterculture gathering of about 1,100 people in an eastern Utah slice of national forest.

Federal Judge Dustin Pead, prosecutors and public defenders began hearings in a trailer Thursday, working through 21 minor citations that included having a dog off a leash and drug possession for 17 members of the Rainbow Family.

Legal workers and security agents milled around the courtroom Thursday morning, checking paperwork and chatting in a meadow.

Spokeswoman for the U.S. Attorney’s Office in Utah Melodie Rydalch tells KSL-TV (http://bit.ly/1m58rqU) it’s not the first time Utah’s federal court has packed out to a remote site.

It did so for the 2003 Rainbow Gathering in Summit County and for the 2002 Olympic Games in Salt Lake City.

Officials say they expect the gathering to swell to about 10,000 people next week.
