Non issue with me as I either own or lease the fields and I always walk the perimeter prior to cutting, especially where their are property owners next to them. Seems as though adjacent property owners have no respect for land they don't own. I always get their trash on the borders which I throw back on their property.
Think I mentioned it before but one of the leased fields, the adjacent property owner actually dug a hole for a BBQ pit in the field and the property owner (not me) took the clown to court and he had to remediate the issue at his own expense plus reseed it. People today are either stupid or ignorant or both.
