I got a bit nervous when the first batch was on him. He was really aggitated, and suddenly turned on the trial like he was planning on taking off back up the trail. Even Kristy thought he was going. I jumped off. It wasn't really till then I knew what was bothering him. I thought it was a fly but could never see it. I wiped them off as best I could then got back on and in a short distance he was stomping again. I didnt get off then till he stood still for me, I don't want him to learn I'm going to bail if he acts that way. I just really didn't know what was going on the first time. I had trouble believing those things were bothering him that much.

He probably felt like something had a hold of him. Funny! I'm glad you weren't hurt though. Squirrely things like that can be scarey sometimes.
I had a close one with Bob on Sunday. We were boogying on down the trail at a pretty fast rack when suddenly, for no apparent reason, he bucked both back feet up over his head. Nobody was close behind him. There were no flys. I have no idea why he did it. I was lucky I didn't fall off. I managed to get a good hand full of mane, but I lost a stirrup and it took me a few seconds to get him stopped. And I broke a nail, darnit! ;o)
You might try spraying his legs with WD40 - I don't know if it will work on your weeds but it does help keep stuff out of tails on the endurance horses.
