Yeah, we've got a bunch of random ones around here, too (Shell seems to be popular at places that have grocery stores), but most of the smaller ones seem to have cross-billing agreements. So, while I have a Chargepoint (I've also got a Flex scheduled for install, next month), EVgo, Shell, Blink, EV Connect and Electrify America on my phone, that's mostly for "in case I go on a road trip (I'd used PlugShare to show me what were along my most-frequent road-trip routes). What's within a 5mi radius of my house is mostly EVgo and Shell with several Blink stations that seem to be in the private parking garages of large condo complexes.

Living in Norther Virginia, there's a decent amount of EV and PHEV ownership meaning there's also a decent amount of supporting infrastructure. There's also a good amount of charging infrastructure all the way north on I-95 and even along I-270 and US-11 …until you reach the PA/MD line (then it gets real thin with scattered clusters near Gettysburg, Carlisle, Camp Hill/Mechanicsburg and Harrisburg).
