People stood in line for hours, and some even flew in from out of state, for the chance to see former President Clinton in person.
The line began forming outside downtown Denver's Tattered Cover Book Store some eight hours before Clinton arrived to autograph copies of his new book, "My Life.''
Only customers who had previously purchased the book and had a ticket for today's book-signing were allowed to attend.
Tonight, Clinton spoke at a fund raiser for a memorial to Columbine High School shooting victims.
Clinton was president at the time two Columbine students killed 12 classmates and a teacher before killing themselves in the 1999
He also met privately with family members of the victims.
The former president is expected to help raise 300-thousand dollars for the memorial.
About 700 people and companies are paying 250 dollars a ticket for the fund raiser. Some donations of up to 50-thousand dollars are also expected.
