I text my brother as well....last season on opening day of Shotgun season I shot a nice 8 pt minutes after legal shooting light began..and he sent me a txt "Just like that..." It was pretty funny...
Most times I will bring a radio with earphones and only turn it on around 8am(to listen to some hockey insiders) and thens shut it down....and in the afternoon...I will listen until there is about an hr of light left, then I shut it down...and I ONLY listen with 1 ear...very low volume...
Also, I always have mini chocolate bars or granola bars and a bottle of water as well...and after Halloween...sometimes some candy
