One guy did a demo circuit in a 185 at 300 feet and cut the x-wind at the edge of the departure and the base at the end of the approach. I guess he wanted to show off his awesome skills but needless to say it was a very painful experience trying to learn from someone who thinks it's all child’s play and has very little paitience for new pilots who are just learning.
Unless he was flying wrecklessly Sarah a three hundred foot circuit is quite safe and is something you should be comfortable with if you are going to be flying in the bush or on sea planes.
