Oh - I wear the lycra shorts under my pants... And I think the pants you wear are the same as what I wear.... stretchy stirrup pants that are sortof t shirt material.
I've never tried the ones with stirrups but I'll bet they're good at keeping your pants legs from riding up. I don't generally have that problem, but every now and then I will. I don't really know why unless I'm just putting more weight in my stirrups some days than others.
Oh, I took lots of pictures of the little jack this evening. He was just precious! His mama didn't mind me messing with him at all as long as there was feed in the bucket. He was a little afraid of me at first and kicked at me a time or two but when I started scratching him he decided I wasn't so bad after all. By the time I was done he was coming over to me every time a fly got on him. So cute! I don't know how good the pics will turn out but I'll post the best ones tomorrow.
