Practice can be chaos unless someone with a strong personality takes charge and organizes the event (I know since I worked the practice dock when Nationals was at San Marcos River Ranch - SMRR). People will and do pay money for a proper practice - sites should capitalize on this.
I know I might be picking a fight here (I apologize - not my intention) but attitudes like "suck it up and ski and you get what you get" don't help anyone. And yet we still pontificate about why our sport is lagging?
Sure, if you are a 3 EV (I'm not), or your entire family competes (mine does not), then maybe it makes sense to not care whether you can check out the setup/conditions/water feel. And then fall on your opener.................not for me.
