tips on organizing in a smallish american town?

i live in a small-medium town where nobody really seems conscious. idk if i'm just not tapped into my local scene but i feel like i'd know if there were a dsa/foodnotbombs/etc branch here, i've looked online. i have a lot of desire to do something productive for my community but i just feel stuck and isolated from broader movements. how does someone even start organizing with their community when no foundations already exist?
