I spotted a portable air compressor in Auto Zone today. It's sold by Slime,the green flat tire sealer company. Included with it for $30 is direct-to-battery wiring,and wiring for a quick connect. The size is about 5"x5"x2",too big for the drz tool pouch,but still small enough to consider as something to take along for a long ride. Anybody out there already have one?
