I checked the quick-search and skimmed through the pages before posting. :X Sorry if this has already been done. Feel free to link me to an old thread, if it has been!
I just read an interesting note about treeless saddles, and how you should not mount from the ground. It went on to say that really no one should should be mounting from the ground because it will make your horse look "wrung at the withers" along with potentially making your saddle asymmetrical or throwing the horse's back out of alignment.
I wondered what your experience with this was, and what your opinions were on this subject.
I prefer to mount from a block, but that's because I'm a bit more fluffy than most riders.
