The dear old dentist. Most dentists would be willing to do a 30 minute or so tour of their facility if you call ahead a month or so in advance. This will get your younger children familiarized with the dentist office and they will know what he does. They can sit in the chairs, brush their teeth, get laughing gas, (just kidding) and you may get free toothbrushes and floss! The zoo. (at feeding time is best) You can call ahead of time to see when the mealtimes of certain animals are so you can be there. Take a sack lunch for each of your kids to save on money and have a picnic. Don’t feed the animals! -Just an FYI, the first zoo was built in China, over 3,000 years ago. It was called the Garden of Intelligence- your kids will think you are intelligent for sharing this tidbit!
