i do the same occassionally....but once when coon hunting with dad and our hounds at night...dad and i were listening to the dog work...we didnt have the lights on....dad ALWAYS flicked his light on before sitting down....i started coon hunting at age 5 or 6 no joke....i was tired of standing up lonnnnnng before dad thought about sitting down lol..as soon as i seen him about to sit down i was sitting lol...never turned on the light...didnt know why.......one night i did it...like every night......worst case of poison ivy i ever had......FULL body....face and hands were BAD bacause they touched it......then everything my clothes rubbed on....and then my hands touch...YES even there...........it was full body....steroid shot cured me right up.........but man was that miserable....dad knew what happened as soon as i was itching.....so we got it taken care of rather quick thankfully.....better believe i shined the light before i sat down too......dad told me thats the reason he shined the light first......
