June 20, 2012, 12:06 amThe U.S. Olympic Track and Field Trials start Thursday in Eugene, otherwise known as Track Town, U.S.A. The event will be very popular, with thousands of people expected at Hayward Field everyday. That has police worried. Eugene Community Service Officer Kelly Putnam says the area around the venue will be a target rich environment for car prowlers, but in 2008 when the city hosted the event, there was actually a spike in property crimes in other neighborhoods. Putnam says thieves hit those areas, thinking all the officers would be tied up with the event. She says that isn't the case and both the University area and the rest of the city will be well covered by police.
