Narrative:

I was VFR with destination of 1k1, ks. I had checked ATIS of airport south of tulsa, ceilings and visibilities were marginal but ok (1200 ft ceiling). The WX deteriorated rapidly as I passed tulsa. Rather than backtrack through rain, I decided to land at first available airport. Although I had a sectional in the plane, I was using a government chart. Combined with dusk conditions and poor visibility, I was unable to determine exact position. I called mcalester FSS, they had me squawk 7700. I knew my radial and DME from tulsa VOR. I was transferred to tulsa approach who immediately gave me vectors to sand springs, which was 4 mi at 80 degrees from my position. In approximately 1 min, airport was in sight. Flight terminated uneventfully. Fuel was not an issue. At end of flight, I had 1 and a half hours of fuel remaining.
