^Agreed. Some rules actually make me avoid the barn (ie. EVERY adult rider MUST wear a helmet, etc, etc).
I have it lax! We basically have these rules:
-make sure all horses in the field are safe and healthy, if one's not.... BRING IT UP TO THE BARN, or come and get someone
-Don't touch others stuff without permission and if you do then make sure to put it back
-Use COMMON SENSE
Some funny ones are:
Tidy up after you giddy up (clean up the barn aisle)
-Want something special for your horse? Then go buy it yourself!
-Check ALL water tanks/buckets during your stay and BEFORE you leave (people who don't follow this get yelled/screamed at by me AND my boss)
-You get hurt that's your fault, your kid gets hurt, that's your fault, in fact if you come to us crying about how a horse hurt you then maybe you shouldn't be hanging out in a barn!
Those are really all the rules I can think of haha.
