I hope this hasn't been mentioned but my husband always takes with him traveling and to the parks a pack of peanuts in his pocket and I ususally take a pack of peanut butter and crakers especially if I have my grandson. We have to have water! Last year we took the packets of lemonade. We had bottled water but our fridge would not get them cold enough. I read somewhere to ask for the water and add these packets. So I thought I was being very smart and insisted my husband just ask for a cup of water. What was I thinking! You should have seen my husbands face after gulping that down with his thirst. It was awfull! I would rather have drank my water hot or paid 5 dollars for a bottled water than to have drank that stuff! He went and got us something to drink afterwards! LOL! When we have taken our camper we have also taken our water frozen and that does work very well.
