The following images were taken today (and yesterday) just walking back and forth in front of my house in SW Houston, TX. I began taking the shots a few minutes before 5 pm (both days) and stopped almost 30 minutes later.
Another day of activity over SW Houston, after watching a day of activity over Sugar Land (no camera available.)
In some of the shots it is hard to tell that there are planes in there, because it is already so saturated, but look close, you can see finer lines. Right click and zoom to make it full screen...that will help a lot.
Update - I received this email today (5th) after this page went up from a fellow Houstonian:
"I live here in Houston - today I happened to be walking outside, just outside the west loop right around 5pm and looked up and saw all of the trails, including the plane (or one of them) making them! I haven't been on rense.com in a while, but just decided to check in today to see what's new. Glad I'm not the only one who noticed, thank you for posting this! Thanks, Josh"
