No town hall meetings for Walz?

So says a letter writer to the Austin Daily Herald-

"I called the office of Congressman Tim Walz and learned that he will not be holding town hall meetings during the August recess. Walz’s office said town hall meetings are not constructive; he is holding targeted meetings instead."

Suddenly, town hall meetings are not constructive? Sounds like someone is afraid to hear what the voters think of Obamacare.
