I remember the YMCA and can relate to everything you have raised in your post . I too went to Montague street ‘Y’ and did girls club, basketball, trampoline and judo . I also went to Camp Manyung for years where we would hike into Mornington along the beach.
Bev Bruce was a terrific lady and would also often pick me up from home en route to the ‘Y’ when I was younger and I have fond memories of her!
The other activity we did was swimming in the pool in the basement of the YMCA on the corner of Sturt st and City rd, right on the corner where the No1 South Melbourne beach tram went around past this ‘Y’ and headed onto St Kilda rd – All now replaced by the Arts precinct
Your name is familiar Lorraine and so I rang Mum and she remembered your family – It would be nice to talk about those old days!
