Wuwee trackrig you must be in the yeast of Washington. Spokane. Myself I am a yelk eater but would not turn down meecemeat. I rate moose right behind grizzly as being hazardous to a person's health.

Higher antimony cyclable flooded batteries self-discharge significantly faster than 1% antimony engine starting batteries. But a chilled battery loses it's appetite. The difference between 50F and -10F can be a real eye opener. At -59F we lost batteries sitting in a shed in Ennis MT. Had to breathe through a wad of cloth. Yuk. I'll stay here. Cold and Old does not rhyme worth a ****.
