Ok, we're about a couple weeks out for our trip (Yay!) and I wanted to clear up for myself my original question! I re-read my question and what I guess I was trying to originally ask is, on these highways I mentioned, are these highways straight through meaning they do not have any stop lights on them? Some highways still have stop and go lights that slow you down and we want to avoid them if possible! I know some of you who answered already probably figured that out but I just wanted to make sure for myself since we are going to be finalizing our trip route very soon. Thanks again!!!! :)
