Jungle Strip - I remember the first time I went spinning, it was the first thing I did after my PPL. I was told by the instructor to climb to 5,000ft and to practise slow flight on the way. I got real good at flying very slowly and hardly climbing at all, all because I wanted to delay the spin entry. I could probably have made the climb last longer than the fuel in the tanks! Eventually the moment could be delayed no longer and the instructor showed me a spin, my heart pouding and palms sweating all the way to the stall and spin entry. To my surprise and delight it wasn't nearly as bad as I thought it would be. By the time we'd done another two the dreaded spin dragon that existed in my head hadn't exactly been slain, but had at least gone to sleep.
As with many things, the anticipation and anxiety make it seem much much worse than the reality, if only the same could be said of going to the dentist :-). Book yourself that flight, preferably with an instructor you know, trust and get along with and go for it.
