I had difficulty with map folding so I only flew within about 40nm of the airfield (or 20 if I had a 1/4mil)
The frustrating thing I find is when you buy your chart and its been folded by the club/shop or whatever, so has to be refolded again and always goes back to the previous creases.
Finally, how do microlighters cope with there charts? I wouldn't want to be doing a bit of folding in a flexwing! (maybe one day I'll find out - when I can make my mind up)
