Basspro has several models of heaters to choose from. I' ve been know to use one in a popup or simular blind when my son is with me. He' s 8. Never seemed to hender our success.

Additionally, I' m sorry to here about your bro. My wife is battling the beast as well and I know first hand how hard it is. I hope he' s winning his fight. I' ll say a prayer for him.

Kudo' s to you as well. It' s a great thing you' re doing for him. Getting him out and away from his problem has got to mean the world to him. Keep up the good work, you' re a good brother.
