I think I'm getting a handle on this. I've only had Lance a month and haven't ridden regularly since I was a kid. I think some of this was Lance seeing what he could get away with. I saddled him up about a half hour before my wife saddled hers. I found that when the bridle is back over his head and my hand moves up to the saddle he'd start moving. Every time he did that, I'd grab the bridle up by his face and tell him 'No!'. After awhile he got the idea and stayed still.
It then got worse. If he couldn't keep me off, he'd refuse to go. He kept acting up, backing up, refusing to go and even bucking a couple of times. I think he realized how green I was. Away from the barn he was okay but when he realized he was on his way home he was unstoppable. This wasn't much fun, especially when my wife had to grab the reins and lead him away from the barn.
I recently tried something I'd heard about but didn't believe. I made a fake whip, a tumbleweed branch about a foot long. When I mounted he went into his routine. I held out the 'whip' to where he could see it and yelled, 'Lance - No!'. He promptly went on his way and hasn't given any trouble since. Yesterday I tried riding him down a trail near my house, It comes close to my place and goes away several times following a stream. He saw his barn, recognized it, and was willing to continue. The old Lance would have refused to go away from the barn. It looks like I have a great husband horse.
He got an apple after that ride!
