Location of Lawn Bowling greens in Detroit?

[manualshift]

Detroit was home to at least 2 Lawn Bowling Clubs in 1961 the Detroit Eastside Lawn Bowling Club and Detroit Lawn Bowling Club.

James Bell of Detroit LBC in an editorial dated 1964 identifies location of their field as being at Wreford and Grandriver for over 40 years

There were 42 members until just the other day.
While they were bowling on their usual rink, at Wreford and
Grand River, on a balmy Saturday evening ...
three young rowdies suddenly
appeared, snatched two pocketbooks from
a bench, and ran down the street.
Some of the members gave chase, but
soon were exhausted and gave up and
went home. Two hours later one of them died.

Looking to identify where the green was. Typically these greens are either grass or fields. 100-120 feet long. Typically square to accommodate 4 lanes [[grass fields must be square to allow switching directions from east-west and south-north between games). Clay court need not be square and therefore could have anywhere from 1-4 lanes).

The Wreford looks from Google maps to have an area at the corner of Grand River that might have been a clay surface at one point [[I suspect but it is not clear. I am also not clear on the size of this area). Looks like it has been paved over and is being used as some type of skate park.

It appears from a guide to the city that there was a field at Conner Playfield near Gratiot. However I can't find anything more specific on it's location.
