Very handy for surviving the zombie apocalypse!
Yeah we learned this in the army. Gives you a general idea of how much time till sundown
Since I always forget to wear a watch, this is fantastic!
that's actually really helpful... but i haven't seen the sun in a while... is it still yellow??
i was getting a bit tired of wearing my watch. thanks for the tips.
hope i will not need this in any near future..
