Yup I know exactly where you mean. That’s the deadly /haunted Tolland triangle where all the accidents and deaths occur. Basically as soon as you hit the top of the hill until exit 68. Hundreds a year .
That area past 68 into Willington area is lower. It’s where MPM’s Electric Blue Cafe is . It dips down to 500 feet until you get past Willington. Willington is overall a lower elevated town.
Ive got 6-8” of concrete here . No grass showing anywhere in town either , except on due south facing slopes and it’s mainly like leaves/ rock/ ledge
