Just realized I haven't hung out with friends in a year

Was scheduling my calendar and it hit me - no actual friend hangouts in like 12 months. Just work, kids, home, repeat. We moved to the burbs 2 years ago when our son was born and I haven't really built a friend group here. Wife has her mom friends, I don't have a dad group or anything. Feeling pretty lonely ngl. How do you guys make friends as a dad when you have literally no free time?
