I watched KFOR's live coverage of the OKC superthunderstorm last night. Transfixed for 10 minutes or so... during those 10 minutes, lightning flashed constantly at a rate of about 3 per second. That's 1800 flashes in 10 minutes.
Compare that to Spokane. We get about 3 thunderstorms per year, and each storm has about 3 lightning strikes audible from my house.
At that rate, Spokane would need 200 years to beat those 10 minutes of one storm in OKC.
Admittedly this storm is considerably more flashy than the Okla norm, but not unprecedented. When I lived in OKC and Enid, at least one storm each year was up to this standard.

This piece of the Weather Bureau's record from Tinker tells the impressive story.
Absolutely everything was happening. Every type of weather except sunny. Three inches of rain in one hour, followed by two more inches over the next few hours.
