I finally got new wheels on the cart I got, and even though it still needs a seat cushion, I decided to take it out and see what Bandit thought of this new contraption.
He hasn't had his harness on since last spring, so I started him out with that, and he's still pretty unhappy about his bit, but he took his harness and bit like a champion. The check rein is still too short, though, so I'm not bothering to use it for now.
Then I had my friend pull his little cart around and rattle it -- we made as much noise as we could with it, at one point even picking it up and dropping it so it'd rattle, until he didn't care (which only took a couple minutes). We pulled it in front of him, behind him, all over, and finally I backed him in between the poles and rubbed them all over him, bumped the cart against his legs, and everything. We desensitized him to everything that we could think of that could possibly happen, and he took it all in as if he'd been pulling carts for years. I finally attached his harness to the cart (but left the traces loose) and had my friend push the cart behind him as I led him, and he only got a little worried. Finally, when he was walking normally and wasn't concerned with the cart, I attached the traces and led him around. No problem! He took a bit to get the whole turning thing down (and I wasn't overly concerned with that just yet, so I let him be), but eventually he even figured that out on his own!
Unfortunately, the other horses (across the road from us) suddenly got really upset (I think a storm is on it's way; they usually start stampeding about when one's coming), got Bandit all upset. I didn't really want him to rampage about with the cart, so I calmed him the best I could, undid his traces, and walked him out. A section of the harness caught on something (I'm still not sure what), and he ripped out part of the stitching. (The harness is sort of old -- we got it at an auction) So I'll have to take it in to get repaired, and while it's in, I'll have a slightly questionable strap replaced. (Fortunately, I work at a tack shop -- employees get free repairs, and discounted hardware.
I'll have to find a tail bag or something, too -- I guess I didn't realize how long his tail was until he was in the cart.
Anyway, no more rambling; I got a picture and a short video!
(The traces and stuff are all tied up, so they didn't drag or get tripped on.)
