Oh yeah, but OT a tad... I remember my first higher hunt.. flatlander from 200 ASL Texas... went with a buddy to above timberline on sheep mountain across from Pikes Peak...
Anyway I had a tent, and candles for a bit of light.. but the dang candles would not stay lit or basically light at all.... I couldn't figure out why, till my buddy from Florissant told me how dumb I was... And I learned more that night, not being able to breathe.. stopped up etc.. and then the next morning I made it about 50 feet to a boulder to "glass" instead of bowhunting the bucks..... It not only whipped the candle but me too...
