Hood River County Chamber of Commerce Executive Director Mike Glover says based on response to a survey of local downtown businesses and anecdotal evidence, business has been down 30 to 50 percent during the Eagle Creek Fire and closure of eastbound Interstate 84 compared to the same period of time a year ago.  Glover says a brief survey the Chamber did of downtown Hood River businesses showed found a basic trend, with the majority saying the impact of the freeway closure was negative but not catastrophic.  Glover said 52 percent of respondents said they had not had to lay off anyone at this point.  He said the Chamber is looking at various different marketing ideas to be ready to promote tourism after eastbound I-84 does reopen, noting Hops Fest has been rescheduled to October 7 and Harvest Festival is set for the following weekend.
