Saint Patrick's Day is on Friday, but Deadwood is beginning the celebration on Thursday.
Deadwood is kicking off the festivities with a benefit auction for the American Cancer Society at Saloon No. 10 on Thursday.
Friday is the Leprechaun Olympics, and Saturday is the parade and pub crawl.
Amanda Kille from the Deadwood Chamber of Commerce says events like this are prepared months in advance before the date is even made public.
Amanda Kille says, "People don't realize how far in advance that our staff, especially our events coordinator, is working on an event like this. You've got to get the help and cooperation from the city departments, from the police departments. You've got to have security hired. People are working on floats."
