Slipping but not enough

10-23-04 Three solo pattern flights, working on landing without flaps or air brakes. Could not get in touch with the instructor, it turns out she was out of town and had scheduled to fly Sunday. Each time, I ended up too high and had to use the air brakes to get down. One time, I floated beyond the boxes and decided to balloon over the taxiway and land in on the far side. The slip seems to be far less effective than the flaps and brakes. Need to do this with an instructor!
