Yes!!! Avoid this at all costs, it seems like a fun idea... but I boarded at a place up here near Albertville that had that. My mare liked the arena because she felt good having the horses in their stalls while we rode... but... the footing was Airfoot, which needs to be watered every day to keep dust down, or else there is a lot of dust with rubber particles in it. I could not ride in the indoor much at all (I have videos from lessons where my trainer and I are out riding in the pouring in the rain, we both have asthma). My mare's stall was on the arena and she ended up with long term respiratory issues, and I treat her for them now, almost 5 years later.
My gelding, luckily, was never stalled on the arena, their stalls did not have doors and he could get underneath the stall guards, so I kept him in the main barn with the race horses so he could have a door. He suffered no respiratory issues.
