I can just see Janie's new gun cart now.
Pulled by a case steam traction engine with its attendant water trailer, capable of carrying everyone's guns all at once, steam whistle loud enough to crack your teeth, and a trailer on the rear for staying over night or over the season, complete with a pool table, whirlpool bath, gourmet kitchen, and a moderate workshop and photo lab.
Don't worry about enough energy. She has enough to go around.
