Most of the time it is not really a problem and I've managed to either wait for people to clear the area or throw well enough so that there was no chance of hitting them. There is a totally blind throw on the new course that I've called fore on. Somehow yelling "fore" and then landing the disc on top of someone's lunch seems like bad form though, lol. (I think they should reorient one of the baskets a bit and perhaps shorten the drive so long shots are not potentially drifting over towards popular parts of the park.)
