Good for her! Looks like she was having heaps of fun (lovely horse too :).)
I have asthma too, annoys the heck outta me and get it from dust, a cold, nature, running, swimming (that's a pain because you can't breathe underwater and can only quickly gasp and not get anything in: 'Swim faster!' 'Could YOU if you had no air?!') so I feel her pain. Oddly, horse riding doesn't really make me wheeze much at all despite the dust and the horses and exercise I would usually react to.
