The problem with eclipse chasing is clouds. It could be that Dallas in April 2024 is slightly cloudy and if you drive just 30 minutes south you will be able to see the sun. Sounds like you are coming from far away specially to see this eclipse, which I totally respect!. If I were coming from far away and did not know how to drive, for a place like Dallas, I would either learn to drive and get a driver license before coming to Texas, or I would hire a car and driver for the day.
