The bar compresses Independence's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the April 18–May 9 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 13. Wherever the today marker sits, the nearest color change is your next appointment.
