Welcome to GMRS!
As you can see, some of the more vocal members of this Forum continue to press for their personal preference that GMRS is "bring your own contacts." Whether or not this is historically true, the fact of the matter is that many of the newest members here are expressing a preference for the ability to reach out and have non-family/friends contacts with other GMRS licensees, too.
Some are motivated to setup new repeaters in their areas for just that very purpose.
And in some geographical locations, such as Southern California, there are many established repeaters that allow and encourage non-family/friends contacts; such as the Club650 and the Santiago CREST 675 repeaters.
YMMV and good luck with your use of GMRS!
