One last consideration if taking that bridge over to CC (and then south from there). You need to remain at least 1000' (and 2000' to the side) of the highest obstacle in any congested area. That doesn't leave you a lot of room if you're trying to stay under the 1200' shelf of CC airport. One other consideration is that upon zooming in further, I see that this area is surrounded with the shaded magenta lines, so it's Class G to only 700' and then Class E above that. So between 700' and 1200' you'd have different cloud-clearance and visibility requirements for E: 500' below, 1000' above, 2000' to the side; and 3 SM visibility. But you'd be in controlled airspace.
But oh man, I just ramdomly clicked on the city of CC and I find that there's a Class D airport (NGW) almost hidden right there between CC and Waldron. And it goes up to 1200'. So my preferred route doesn't work if you don't want to use your radio to ask permission to transit NGW's airspace.
I don't think there's any way other than going around CC if you're set on not using your radio or you don't have a transponder+ADS-B. And I'd do it on the weekend so A-632C is not hot for sure, and then I'd get below 6000' to go under A-632A.
As a side-note: I just went over this with a CFI friend in TX. All the twists and turns and considerations. He's going to use it for his students.
