Available in PDF, EPUB and Kindle. Book excerpt: Long-term recreation planning requires an understanding of recreation participation patterns. This study examined Vermonters' participation in 27 leisure activities from three domains (outdoor, resource based, and indoor) to see how such participation differed in each domain. Indoor activities were the most popular, followed by resource-based activities and general outdoor activities. Overall participation declined with age, though this effect was mitigated somewhat for older parents. Other socioeconomic and demographic variables had limited effects on participation.
