The streets were quiet this Halloween in Isla Vista, with only about 500 partygoers roaming Del Playa compared to 12,000-15,000 in 2013. Pending final numbers, Santa Barbara County Sheriff’s spokesperson Kelly Hoover said 16 people were cited, and 28 were arrested for misdemeanors over a two-day period. Last year, I.V. saw 40 Halloween weekend citations and 40 arrests; 250 citations and 200 arrests were made during 2013’s three-day operation. Only seven partyers were taken to the hospital this year, which the Sheriff’s Office said is much lower than in years past.
