Weequahic Park was known, among other things, for its sleigh riding and ice skating.  
It was also used as the home field for the Weequahic High School Soccer Team.

From Stan in Texas:
I have many memories of Newark but I'd like to tell you about my experiences at Weequahic Park. My father first took me fishing there in 1949. We fished off the shore close to the Elizabeth Avenue entrance. We caught nice sunfish and calico bass. The area was nice and the fish were always biting. When I was 16 I fished off shore and I rented a rowboat from the boat rental area near the Frelinghuysen Ave. entrance. I remember the race track. The last time I fished there was in 1970.
