We use cell phones and a bluetooth in the truck. It works great! So far we haven't been anywhere we don't have a phone signal. I suppose we will have to do hand signals like we used to if and when that happens. I have thought about walkie talkies as a back up plan but just know I probably wouldn't be able to find them at the last minute. They would get shoved somewhere safe and I wouldn't remember where I put them, or, I would find them and the batteries would be dead. I guess my best back up plan is hand signals and a patient DH!
It is fun to be all set up in camp and sit and watch people come in and back in. Almost as fun as watching people launch their boats!
I enjoy watching the efficient people and try to learn from them, but really enjoy the inefficient ones as they make me smile! I thank heavens that DH is really good at backing up!! Lord knows if I ever had to do it I would be giving quite the show! LOL!
