Narrative:

Dialed wrong tower frequency. Landed without radio contact. Discovered error via ground control frequency. Contributing factor: I thought: they don't answer because they're out to lunch, downstairs playing cards, not operating on friday, etc. Rural airports with low traffic. Little did I know!
