We attempted to post up at Dupree on the river for our inaugural spring camping trip, but was not able to enter the CA the usual way from St. Joseph off Highway 36. Our first attempt at entering was via the North on Airport Road (then 26th Road north 0.75 mile, and DuPree Road east 0.75 mile), but that led us to a locked gate with a sign that said something about a levee. So we exited back out Airport Road and headed SW and attempted to enter via Vermont rd. We found where they were digging the levee and were not able to pass through this route either (gates, sign, mud, federal prosecution from entering levee area) - but we saw this cool train bridge !! Short story long, we didn’t camp at Dupree but will try again next year :)
