The bar compresses Asheville's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the April 7–April 28 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 17. Wherever the today marker sits, the nearest color change is your next appointment.
