Heard from Dan O’Sullivan that his brother, Sonny O’Sullivan, passed away last night peacefully.

Sonny was a prominant figure and fan favorite in modified racing at the legendary Riverside Park Speedway in Agawam, Massachusetts back in the 60’s and 70’s.

R.I.P. Sonny O’.

It seems like he drove everything at some point. I know I raced sprints with him, but I also saw him go in LM and Dwarf cars. RIP racer.
