Some communities give out service awards to volunteers. I recently became aware that in Pierce County, WA, the United Way gives out "Green Feather Awards" to individuals who volunteer over 100 hours a year. Several of our regular volunteers received a certificate (complete with the number of hours they volunteered) and a nice lapel pin. I thought this was a great idea for regular volunteers! Try the United Way, the local parks administration, the city offices, established service clubs (Rotary, Lions, Kiwanis), etc. to find out if such an award is available in your community. It's really suitable for volunteer interns (who often rack up hundreds of hours over several months) and for college students, who can list the community award on their resumes!
