With a burn ban going into place in Wasco and Hood River counties on June 1, fire officials are bracing for what could be a busy fire season.         Mid-Columbia Fire and Rescue Chief Bob Palmer said they have dealing with wildfires much earlier than usual, and the tinder dry conditions increases the danger.  He adds recent rains have not really helped the situation.  Palmer noted most of the fires local crews have dealt with this spring have involved burn piles getting out of control.
