y'know, was thinking about having a hover obstacle course at our fly in in lakeland; a kiddie pool to touch the tail in, see who could do the most touches in it in a minute. a harrier slalom course with balloons holding 15' of crepe paper 20' apart. a 8'x8' limbo square that would have to be flown through. stuff like that. nothing really structured, just a challenge for the guys...
