Lawn bowling was "BIG" in the golden era.. the mansions all had set ups on their grounds. I think now it is more or less a historic interest item.. but perhaps again there may be more to it than I think.
The folks I know who are bowlers are into leagues & do it regularly at lanes that are totally computerized(no more cheating..hehehehehe)
I did a fair amount growing up but was never drawn to it. Now that my back is weird, I have NO desire to stir it up with something like that
Regarding lawn bowling I suspect that there would be a US league or local leagues somewhere possibly New England from the photos that came up at google.
You may also have a national team because it worldwide sport it may even be an Olympic sport. It is certainly a commonwealth event.
