No, I wasn't referring to you or your bestest friend. You guys do a great job parking, and having the walkie talkies like you have is a good idea. We have them also and use them when necessary.
But like you said, going slow is the way to go. What's the hurry? If I don't see Rick I stop until I do see him. He knows when I'm not moving to make himself visible. I want to avoid running into something or someone.
Remember to watch the front also. It's easy for me to lose sight of someone walking closely around the front.
