Oklahoma State Capitol (working oil derrick grounds)
Oklahoma
Every state capitol has a dome. Only one has an oil derrick in the front yard. Oklahoma's is the sole U.S. statehouse built directly atop a working oil field -- the 'Petunia No. 1' well (named because drilling started in a flower bed) pumped from the grounds for decades. The capital check-in here is the anchor Roamward stamp for Oklahoma: dome, derrick, and the story of a state literally built on oil money.
Why Roamward picked it
Capital check-ins are a core Roamward game mechanic across all 50 states; this is the mandatory OK capital pin, distinguished by the oil-derrick hook that no other statehouse can claim.
