Some places even have a lost and found but people posting here aren't even saying that they are lost. They are saying they were left behind. There is an easy direct connection to the owner and that is at the office. How many experienced campers pull away and just happen to leave the exact items that would let them easily hook back up after they return from shopping or whatever. If someone pulled out with a FW or TT and I noticed a couple lawn chairs folded up leaning against a tree I'd assume they forgot them, from there I could just leave them alone or I could take them to the office or tell the office. It would seem that the management would check the sites after people vacate also. The office could call the person and see if they will return for their items. As an RV'er it doesn't take long to catch on to how RV'ing works and one of those things is that people in B, C or A may leave stuff laying there when they drive that vehicle away. I see it in desert with the closest person a 1/4 mile away from the items.
For the last 2 years I have seen an older couple parked in the desert near us who leave a propane tank, chairs and a Jeep sitting there when they leave in the TC, it looks like DW will be following me home in a late model Rubicon next year.
The most surprising thing is to hear of this attitude on an RV site of all places. Yes, the short answer is to pack everything up EVERY time no matter how short of time you will be gone. This is the new reality during the continued degradation of our society.
I guess I never really wanted to believe it when in the past I have read of people who travel and believe that they are actually helping a person "lighten" their load in life if they take (steal) some of their belongings. They justify this idea or make a parallel to the Native Americans who considered it a burden to posses too much. Sounds like forced "Redistribution". Now if they could get the government to enforce it what would that form of government be called? Huuummmm...........
