Storm chasing can be very frustrating. On this day we had been chasing storms in West TX. We had seen nothing all day and were gettting discouraged. A large storm developed several hours to our west, causing us to have to relocate even further from home to get to it. When we arrived this is what we were greeted with. It made the whole trip worthwhile.
