1800ed, I learned in the US 18 months ago, at a fully towered airport with 7,000'+ runways and on return to the Uk bought into a 150 and fly it from its grass strip, 800m with trees at one end and a single oak tree on the centreline at the other, with both thresholds slightly higher than the rest of the runway, a road and railway line alongside and under the combined MATZ of two busy RAF training airfields ... my 'training'for this was the check ride on the 150 with the guy who's share I bought. Challenging, but easy after a few landings.
I don't even think twice about this now, and have no problem in realising it's so much safer to go around if you're not happy with first attempt, I did it in training and have done it over here, last time was at Breighton, during their fly-in, in front of so many people... no worries
PS - if you're up in Lincolnshire and want to try it out ...
cheers
