The bidding process for an ambulance remount has hit a bump for Warren County EMS. “We opened the bids Thursday morning at 10 a.m. and we only had two bids,” said EMS director Preston Denney. “I got a phone call from one of the bidders and an email later that day.”First Priority, the high bidder with $109,400, is disputing the bid submitted by Foundation Ambulance. Its bid was $102,613.
