we pretty much have all of those and the one that says inverted arials are not recomended, someone wrote landings over arials so now it says "inverted landings are not recomended"
No signs like those, we do have one that basically goes over what each designation by each feature means, and the beginner area has a sign that last said "Snowblading can be hazardous to your reputation."
we have a little ornge circle, and then all thgese little 5 year old racers go and try to hit our table and they land like 2 feet after the lip in a hole on a up hill
