Oregon Senator Ron Wyden will hold a town hall meeting in Hood River on Saturday, March 25.  The town hall will be at the Hood River Middle School auditorium at 11 a.m.  Meanwhile, a group of seven different Gorge area advocacy groups say they will hold a town hall meeting in Hood River on April 8 at 4:30 p.m.  The groups claim Oregon Second District Congressman Greg Walden has not responded to calls for him to hold a town hall to address constituent concerns.  They say Walden has been invited to attend.
