Cars lined O'Byrnes Ferry Road from the Tuolumne side of the bridge to the entrance of Calypso Bay for the BUMP V party at Lake Tulloch Resort Saturday June 23, 2012. Traffic was slowed as pedestrians blocked the roadway walking in large groups. Homeowners in the gated community along O'Byrnes complained that pedestrians were urinating in their yards or leaving bottles full of urine alongside the roadway. One call at 12:39 am was made to the Sheriff Dept reporting a trespasser on Poker Flat Rd had assaulted the resident and a bottle was thrown at him.
The event that began at noon had warranted no less than 6 medical calls by 10:00 pm. Sheriff logs report 13 contacts resulting in six arrests.
According to Calaveras County planning resort owner Cattaneo did not apply for a Calaveras County conditional use permit for BUMP V. Cattaneo stated, "I operate a resort with a bar (that has three separate liquor licenses) and a restaurant. The Spring Ride, Biker Bash, Bump Party are all part of my day to day operations. We have the zoning as well as all the proper County Business licenses and health permits. We have insurance and County services. We do not allow outside food vendors, public services and don't shut down any roads."
Private security was on the grounds as well as resort employees dressed in security shirts. Some employees under the age of 18 also wore resort security shirts - California law allows no exceptions to the age requirement of 18 to act as security.
