My 2 cents from Sweden.
There are about 66 clubs in Sweden, about 90 000 lakes plus coast. All cost and many lakes are public water.
Few public courses that I know of.
Our club run kids ski school every summer for 40 to 60 kids.
Any skier with a club membership are welcome as guest to ski free with own gas (resonable times).
Average membership in Sweden is about type 200 usd per year.
Club is for rent for events almost any day.
Do we grow the sport? Maybe slowly....
Btw.
U21 Worlds. Sweden men slalom places was 1,6,7,14,15,15. Six Swedes top 15!
Hope the sport will grow!
Hope to see some Ballers ski in Sweden in the future
