Just called my border crossing LOL. The officer was hilarious:
"You need to be seeking admission to the United States. Do NOT tell us you are turning right back around. Go get a drink, go get gas, go to Wal-Mart, but do NOT tell us you are turning right back around. Do you see what I'm saying?" LOL.
She was hilarious. I think I'm just going to save the hassle and do everything at once haha. I'm glad she was funny and nice.
