I'm coming from Seabrook, and will not have the girls with me on Friday. If you're going 90, it doesn't make sense for you to run up to Sealey, because I would normally go out 90 myself, passing through Missouri City (roughly) anyway. Sealey at 8-9 doesn't gain me any morning sleep over MO City at 7ish. Let me see how tomorrow goes, and we'll chat later on whether you should wait for me or not.
THis was the route I was considering, although I don't know much about these roads past Gonzales, it's a different route than I've taken before, so I'm interested:
