This bag is one of the best things ever...love mine. http://www.kingston-...&cat=HORSE CART
As for supplies, I carry a regular spares kit, halter, lead, bailing twine, extra "sneakers", and the kitchen sink.
In my spares box are, pliers, leather thongs, hole punch, electrical tape, knife, zip ties, rein and trace splices, and other things I cannot recall.
I also carry, strapped to my shaft, a small bicycle pump.
Did they ship to you? It says on their website that they don't ship to Canada.
