Lower Wisconsin River
The BLM manages 21 of the islands along the Lower Wisconsin State Riverway. You may have camped on one of them once or twice, thinking you were on state land. That's just fine, since these islands are as open for campting as the rest of the Riverway. Make sure to abide by the Riverway's rules, and enjoy your time on this wide, remote river.
