I poked, prodded, begged for years. Then gave up.
It takes a lot of $$$ to put up berms at 600 and 1,000 yards. The flooding the past couple years also took a lot of funds to repair. I fear anything past 300 yards will never happen.
The south range is an awesome site, hopefully one day it will be better.
That said, people that shoot past 200-300 yards are maybe 5-10% of the membership. Spending all that money for a huge minority is not going to make the board any fans.
