heater is packed and 4 bottles. You know one would think that blood flow would be 90% better to hands and feet after the plugged valve was replaced, not! Some post operation effects have been a puzzle to me like higher blood pressure?? Anyway, I've tried to make sure I can sit two days in a heated blind without any bad results happening. Other than some additional muscle pain from the cold I think I can handle it. No deer dragging...no heavy lifting period. Thanks for all the concerns and suggestions.
