I just posted the 2018 US Nationals event ... it will be held in Virginia. That's new, right?
Yes, this will be Chesapeake Croquet Club's debut as a national championship venue. With so many national events on the calendar now the development of this venue (by Macey White) is most welcome.
I like the potential for new backgrounds for photos!
Of note, there seems to be a quiet movement going on. I posted another thread on four-court facilities in North America.
For this century, I think NCC, Buffalo, Ponte Vedra and Chesapeake are all new additions. Not sure when Tulsa would have expanded to four. Anyway, with facilities being the primary need for the sport, it looks like a nice trend.
