Trespassing neighbor

I dont know what to do anymore. My neighbors cross into my yard as a short cut to walk somewhere (gas station maybe?) I live on a busy road. Theres only 2 houses. Mine and the trailer next door. The church nearby owns it and uses it as a sort of halfway house for troubled men trying to get their lives together. The program is designed to help men who have struggled with addiction or are recently released felons. (I'm not thrilled obviously but I'm not going to judge people that are genuinely trying to do better either)

Because of this, the group of men that live there change OFTEN. I'm a single girl. I live alone. I dont want any issues, but even if I did address them, theres a new group the next month that does the same and I would have to address it AGAIN.

I have indirectly tried to address it by parking my cars along the property line so they get the hint to go around. I cant put up a fence because the county has an easement.

The neighbor just cuts into my yard CLOSER to my house now that I've moved my cars. He literally walks right in front of my garage now then up my driveway instead of up his own.

Maybe I'm overreacting because he isnt harming anything but it just feels like such a violation.
