Why this matters for B2B

Sun-hour geography drives real B2B demand. AZ / NV / CA / TX Sun Belt cities lead in outdoor gear, patio & pool product, cooling appliances and UV-durable materials. Convenience-store gas station demand (see Sales Network) also concentrates in AZ/NV/TX where drive distances and heat lift beverage and shade-product sales. Cube-Age's Houston hub (El Paso #5, Texas cluster) is directly in the sunniest corridor.
