There was a similar horseriding place a few towns over:

- osm.org/edit#map=18/40.66984/-75.71313

Do you believe that one is tagged correctly too?

(I tried to tag the arenas as well according to the Wiki + I checked images on their site to try and see what the inside of that building was.)

Thanks. I am very new to OpenStreetMap. (Only started 2 weeks ago!)

I'll adjust this similar to the one you linked to. Thanks. :)

Note: This was the very first horseriding place I ran across too, so guess I just chose:

- Horesback Riding

in ID, and assumed it was for buildings.

(I was just marking all buildings in the area as best as I could, comparing/verifying data with Google Maps.)

Absolutely crazy the amount of granular detail you can go down to in some of these building types.

Thanks again. :)
