I grew up on Bendell in the 70's and I believe I know that park you are talking about. Kind of hidden away almost enclosed by duplexes? Fun neighborhood in the 70s. Went to Bonner Elementary, played Little League in Freeway American, bowled at Mimosa Lanes...and visited Sage often. My mother managed a few 7-11 stores in the area. The only thing left is Bonner.
