The best is straight through. IMHO its easier at rush hour as the cars are moving slower so its easier to change lanes if you need to. Just roll down your winder, put on your blinker, give a nice big friendly wave asking to be let in. Most times it works beautifully.
COmpared to the east coast for the first 20 years of my driving, these folks are MUCH friendlier. I tow a trailer of some sort pert near every day and have no problems.
