On one of my first cross countries in loose formation with another company aircraft, we came upon the blackest horizon I'd ever seen...(so much for my wx planning)
After it started to rain and the vis began to drop, I elected to land in a big field and see what happened, but the other aircraft pushed on as the base was only about 10 miles further up the road we were following (IFR)
The net result was that me and my Bell 47 got completely soaked, while the other guys ended up turning away from big black bast**d 5 miles further on and suffered a heavy landing, downwind in the scrub

You really haven't seen a good TS till you've seen one in Oklahoma!
My weather planning HAS improved over the last 27 years of heli flight, but I still remain a chicken !!!! to this day
