  This paper compares the needs of groups and communities in outdoor settings,
seeking to identify subtle but important differences in the ways that their
needs can be supported. We first examine the questions of who uses technology
in outdoor settings, what their technological uses and needs are, and what
conflicts exist between different trail users regarding technology use and
experience. We then consider selected categories of people to understand their
distinct needs when acting as groups and as communities. We conclude that it is
important to explore the tensions between groups and communities to identify
design opportunities.
