When the Fourth of July lands on a Monday or Tuesday people will often start their family camping trips on Friday night after work and celebrate together all weekend long and will continue through the holiday itself. This provides an excellent time for a close family to invite their extended family to reunite. A camping event is a great way to build family ties.
The work week ends early if the Fourth of July is on a Thursday or Friday. Families head for their camping spots knowing they don't have to return to the work frenzy until the new work week! Camping sites become very scarce in some of the more popular camping areas and this forces many families to travel to new area further from the beaten path. Because of this some families reserve campgrounds years in advance. Private individuals with extra land including cattle farmers, ranchers and wheat and hay growers will often lease out huge plots of land for Fourth of July camping sites and family reunions.
Land owners with property generally have relationships or common friends with the people they allow onto their property with a basic understanding that the camping groups will leave the campsites clean and in the same condition as when they arrived there. When using private land for camping it is important to maintain the trust of the owners. If you are camping in a national forest or state owned land you will want to do the same and keep the place nice so that your family will be able to take future camping trips there.
