Can I find a bike trailer made in USA?

I believe Burley trailers are still made in the U.S.A.

EDIT: Per their website, Burley trailers are made in China and the Philippines.

Try CycleTote (www.cycletote.com) or Chariot (www.chariotcarriers.com). Both are a little expensive, but look to be much higher quality than your standard Wal-Mart Chinese garbage.
