I will admit that on a couple of occasions when I had intended to do circuits I found that it was to busy and decided to go elsewhere or do something different. I find in general it is quite ok. Remembering that at YCAB, a radio is not a requirement and as such there is always the possibility of there being an extra aircraft or two around. I still wouldn't call it crazy though. Having learnt there I thought all airfields where like that until after I had completed my Xcountry. I must admit it is sometimes a pleasant change to go into some of the quieter airfields. But then I am always thinking that it is to quiet, am I on the right frequency, where is everyone, am I at the right airfield. LOL. Never happy I guess.
