Our family will be in Norfolk from August 1st through 8th, as my son is scheduled to participate in the AAU Track & Field Junior Olympics. We will have our car. I am looking for two types of suggestions related to family vacation activities. First are suggested activities within (or very close to) Norfolk for days when my son has 1 or 2 events. Second are suggested day trip activities up to 2 to 3 hours outside of Norfolk. We will be traveling on a tight budget, so suggestions with nominal entrance fees or costs would be appreciated. Thanks.
