Absolutely. This is Arlington National Cemetery where military personnel are buried. It is maintained by the Army and done with honor. I have attended many funerals there and I can assure you, many tears are shed.
Do people go and grieve over their loved ones? Definitely. Every. Single. Day.
The wreaths were donated by one man and eventually, the press found out, and now, much of the money is donated to the event and volunteers go and place the wreaths on the graves.
Most cemeteries that I go to are cared for. I am sure there are some that have been neglected, but, my experience is that most are not. Thank you for stopping by! Have a nice day!
