To kick off summer, the South Dakota Department of Game, Fish and Parks is encouraging families to spend the weekend outside during the Parks' Open House Weekend and Free Fishing Weekend May 17-19.

During the annual three-day event, anglers can fish without a license anywhere in the state, and entrance fees are waived for all visitors to South Dakota's state parks and recreation areas. Camping fees still apply. Fishing regulations and limits apply.

Open House Weekend coincides with National Kids to Parks Day and special events are planned for parks across the state in an effort to get kids outside to discover the history, nature and adventure right around the corner or just across town.
