Boys: What are we doing today?
Me: First stop is a few minutes away, just on the other side of the Mississippi River... Cahokia Mounds State Historic Site. It's a World Heritage Site, too!
Boys: Mounds?! *groan*
Such negativity! I assured them that this place was much more interesting than our first encounter with mound builders at Effigy Mounds National Monument in 2011 (read that blog post here). That episode is not-so-fondly remembered as our worst national park visit EVER. We hiked uphill in hot, humid weather and battled blood-sucking mosquitoes to see grass-covered bumps which didn't look like much of anything from ground level.
OK, so maybe their groaning this morning was justified...
