This pertains to any and all guys driving down I-35 Friday Night/Saturday morning in the AUSTIN/GEORGETOWN AREA.
TAKE THE 130 TOLL ROAD. You get on in Georgetown, you get off in Buda/Kyle.
It will only cost you $9-$10 dollars if you just zoom through. You will not get pulled over if you dont have a tag and pass under the cameras, so do not stop in the coin only, unless you want to be left behind by your caravan.
I35 is going to be shutting down at random points all through the end of the weekend in the Austin area. Lower Levels closing, etc, etc. This will happen in the early evening thurs/friday/saturday.
Its best to just take the toll. It literally is one of the most badass roads to drive on. Its straight NEVER traffic, and its 75MPH!
Just do it, save yourself the headache.
