What July is like
July is the warmest month and the busiest one. The Fourth of July parade fills the village with people, and the river is warm enough for swimming from sandbars (never in the main current). Prairie flowers peak on the upland savanna and dragonflies patrol every wetland. Afternoons can be hot and humid, so plan outdoor time for mornings and evenings.
