FRS 2-way radios is the way to go.
I suggest/recommend Motorola's line of FRS radios after several issues experienced with some other brands.
I belong to a couple car clubs and we go chasing around in the mountains. In a group of 30 or so cars, there is a variety of FRS radios among us. To date, the "MOTOs" have yet to fail, unless the battery is run down of course.
The FRS radios work well - line of site up to a mile as advertisements claim. (but I've sat on one mountain top in CO with line of sight well beyond a mile to other members of the party - no issues beyond at least 2 miles. But, in the deep woods...a mile is pushing it. All depends on the terrain.
