BACK in 2000 we had a full size coach and bus park in Market Street in Okehampton. I worked for what was then Western National, and we parked our buses overnight in Market Street. At least one coach company, Taw and Torridge, parked its coaches there as well. It was fine — lots of room for turning vehicles and passengers could wait safely for their buses. Then Waitrose came along. It was one of the conditions of the planning permission that because Waitrose wanted to build its store on the Market Street car and coach park, it would replace the coach parking facilities by paying for another coach and bus park to be built nearby in the town — it never happened. Waitrose got its store, local politicians slapped each other on the back. Everyone was happy, except the coach and bus companies, who now had nowhere to park their vehicles.     Mill Road is a terrible place to have a coach park. How are PCV (Passenger Carrying Vehicles) drivers supposed to reverse their vehicles into the parking space without obstructing all the other traffic that uses Mill Rd?  Still if the local politicians say it's OK, then I guess it must be.   John Parsons Westbridge Close Okehampton
