Netty,
I am the least graceful mouter you can see. I recently injured my lower, rightside back and this makes lifting my LEFT leg really hard 'cause you are torqueing from the right side to lift it. I litereall am incapable of lifting it high enought to meet the stirrup and even if I did, I would not be able to push hard enough to mount. I must find a mounting surface.
I get on from logs, little hills alongside trails, fences you name it.
I made a cute little video about mounting from mounting blocks .
Ever have trouble mounting at a block?
