Live trap them.
Seriously, you can trap them in a cage trap, drop a tarp over them, and transport them anywhere.
25 miles or so, is far enough away that they won't come back.
Skunks are VERY docile in a cage trap, and far easier to dispose of/move that way than trying to shoot them and hope they don't spray, as there is no "no spray" guarantee shot.
VA has it right. I too have live trapped many. You can wire tie a tarp around a live trap with the door that opens when turned upside down. Have a flap of tarp for the door too. When you have a victim just approach from behind and lay the flap over the door. The skunk will see nothing and you can transport it anywhere. On release just set the trap on the ground and slowly turn it upside down. The door will open and you simply allow it to leave. .Never had one spray....
