Sorry for the legnthy post, I miss horse talk and love to share my knowledge.
Lapeerian - I think I used the Showsheen stuff today on the horse I groomed, she said it was a "detangler" but I didn't catch the name on the bottle. It definitely worked wonders! Although, I'm not sure how well it would on Spirit's mane/tail - it's pretty bad. You'd definitely have to spend some time picking them out before using that stuff. He looks like he has dread locks! LOL
Cowboy Magic also makes detanglers too, along with some other companies. With Spirit's mane/tail, it can be done. The Arab mare has lovely long, thick mane and tail (white of course). WIth her hair being so thick, she is constantly losing/regrowing hair, which causes major dreadlocks. One day when the mini stud decided to run through our fence, we turned them into their stalls/paddocks. Her paddock is loaded with burdocks. She had burdocks matted into the dreads. Hubby thought we would need to cut her mane (the horror!). It took a couple hours, but they all came out. Spray the hair/dread/burdock mess to start with, it helps work them out. Just don't completely soak the burdocks, then it becomes a mushy mess. You may want to wear some gardening gloves too, or else your hands will hurt/itch from bits of burdock getting stuck in your skin.
The falling off isn't so bad. It is hitting the ground I hate!! I am so due for a tumble. Friend I ride with got bucked off(not my horse!) broke 8 ribs, her collar bone and had a pnemothorax. AAAUUGGHH!!
My Showsheen fall-off was when I was about 15 and I was very lucky. Some kids were playing under the grandstand bleachers, which spooked the horse. He jumped sideways, I held onto reins so I wouldn't lose him and landed on hard ground. In his scrambling around, he end up over top of me. His hind foot dragged hard across my chest. He stepped, but knew I was there and didn't put his weight down. I end up with terrible bruising in every shade of black, blue, purple, yellow and green you could imagine. But nothing broken.
My other bad fall was after college when I was a trainer at a small local barn. I never liked doing it, but I had to train and ride green horses when no one else was around. My mom happened to stop that day to watch for a bit. Bratty colt bucked hard and ducked away so I couldn't catch myself or at least slow the fall, cracked my collar bone. I don't blame the colt, I had started him nicely then another 'trainer' had ruined him with poor techniques. The colt had simply become defensive for his own safety and when I encouraged him to walk on, he retaliated. After that, the farm decided they no longer wanted a trainer. I was crushed and have rode little since. I miss it terribly, that was what I went to college for.
