I used to guide pack trips professionally,now I just do my own for my family.I always try to harber good relations with everyone we meet.The main campground managers know me well,and I always let them know what area we'll be in..If they have an emergency come up (lost hiker) we get a radio call and help out.Be aware.If you come across hikers and something doesn't seem right,stop and ask if they need help.I've ponied afew hurt hikers back to the campground, and rode like a bat outta hell to get more help on acouple occasions too.If your sharing a camp,TALK to the hikers,ask if theirs anything bothering them,invite them to your group for coffee,share trail info,ect.
Basically,instead of keeping a "we're a seperate group" mentaliity,remember that we're all out there for the same reasons,we just got there in a different way
