It's called "Rafting Gone Wild," an unsanctioned event that's promoted on social media sites like Facebook. This will be the third year.
Sacramento County Park Ranger Randy Lewis says it's like Mardi Gras on the stretch between Sunrise Boulevard and River Bend Park in Rancho Cordova…and it's no place for families.
"A lot of excessive drinking, there's some mud-wrestling that goes on on one of the islands, a lot of the throwing beads for the young ladies to have them expose themselves."
Lewis says last year about 10,000 people showed up…and there
were hundreds of arrests, citations and emergency rescues.
"It's one of those things that there's really not too much
we can do other than react to. Last year we had 70 some odd
officers out, helicopters, boats, quads, that kind of
thing."
Lewis says about the same number of emergency responders will
be on hand tomorrow.
He says volunteer groups are planning to pick up the debris
that typically litters the American River Parkway after the
event.
