Zexious, I have a Clydesdale, so I know all about thick hair! I have a a tobiano APHA mare with a thick tail that drags the ground and a mane that rivals my Clydesdales! I have a grade overo Paint filly who has a long, but thinner type mane. I have another overo APHA mare with a thin but evenly long mane. I have an AQHA stud with a long, pretty thick mane, with a ground dragging thick tail. I have an assortment :)
I'm hoping for more length, at least. Thickness honestly doesn't bother me. My fiance has a breeding stock APHA mare with a mane just like this mare. Unfortunately she's just a companion now, we had an ice storm last Winter and she slipped and fell.
Sit tall in the saddle, hold your head up high, keep your eyes fixed where the trail meets the sky, & live like you aint afraid to die, & don't be scared, just enjoy your ride.
