Mowing the grass while the signs are in your possession damages are signs.  We do have to charge a $50 Service Fee for when this happens.  Unfortunately, the grass dries on the signs, and peels the paint off while cleaning them.  Sometimes, week wackers cut the signs.  We try to keep our prices low and signs in great shape for everyone to enjoy!  We do advise NOT to mow the grass when the signs are set up.
