Several bike clubs use Westbury HS on Post Rd as a staging area for rides going East. I have only ridden with them on weekends, and not at all this year, but on Saturdays and Sundays they used to leave at about 7 or 7:30.
The route goes East on the South service road to the 135 interchange, then down onto Woodbury Rd North to Sunnyside and over to Executive (the South Service Rd). Depending on speed and start time, 8 is about the time you would go through where you describe. Then they follow the South service to Crooked Hill Rd and head back.
The return trip through the 135 goes through a small neighborhood at the bottom of Sunnyside.
