2m VHF is good for communicating with family and friends locally but, as you know, both operators need to be licensed. Otherwise GMRS or FRS would be more convenient. For emergencies in remote locations without cell or VHF repeater coverage, you're probably going to have to consider one of the satellite based systems:
As a Ham, there's always HF, which would work over longer distances but it's a little more complicated to set up on a mobile basis and would only work at your rig unless you want to carry a portable HF radio with you. I suppose there may be a way to set up some sort of cross-band repeater system so your VHF handheld could contact your HF base station at your rig and then communicate via HF to the outside world. Whether this is doable or even legal is beyond me.
