Awesome half-day cruiser route. Started at the San Marco "Train Station" and headed south on the S13. This stretch is pure bliss: rolling along the river under thick oak canopies draped in Spanish moss-giving off real "Old Florida" vibes. Made a couple of quick stops in historic Mandarin and Alpine Groves Park, then crossed the St. Johns River over the Shands Bridge. On the west bank, I hit the Military Museum of North Florida in Green Cove Springs (the open-air military gear makes for a really cool backdrop). Closed the loop by heading back north on US-17 and finished up in Riverside at The Gray House. All in all, about 120 miles of laid-back riding, smooth pavement, and interesting stops
