First please know that the D.A.V. does not require a membership to help a Vet, ever.
I am at 70% and rated at 100% because I cannot work anymore. This happened two years ago and I left the Army in 1984. I did not retire from the military. I do live in Florida. When you get a letter informing you are at 100% disabled take that letter to any active military base, post, camp, whatever and get your military ID card. You now have exchange and commissary benefits no matter what state you live in.
With this card you can go to any federal, State, county park and be given free access. Some require a special card issued from that group some do not and your new military ID card is good enough.
In Florida 100% disabled Vets do not pay property taxes any where in the state.

There may be references to departments within the VA that seem to be places to go to get the answers. Not always true or easy to do. The D.A.V. once again, is the best place to get help if you are a vet. Please understand that sometimes Vets get the wrong information from well meaning people. Sometimes Vets get a raw deal and become bitter with the VA. Go to their web site and find your local D.A.V. service officer. http://www.dav.org/veterans/NSOffices.aspx
I know that the organizations such as the V.F.W. and others do a lot of good also. The D.A.V.'s primary business is Disabled Veterans. I found a US Navy Seal leaning on a counter frying eggs in a little Bar called Chaps in Bunnell Florida. I took him to the D.A.V. located at Flagler Beach Florida and in about four months he quit the cooking job. He had worked with a Veterans Department officer several years back and was bitter that they never did anything for him. When the D.A.V. got done with him he got a back pay check for about $60,000.00, his wife got one for about $25,000.00. And he was made 100% disabled and receives $2,924.00 per month which by the way is non-reportable, nontaxable. He also was guided in the preparation for Social Security disability. He is now 62 years old and 100 disabled with the Social Security Administration. Please do not wait to contact the D.A.V. for you or for another Vet you think has a reason to see about VA Benefits. One more thing, there are educational benefits for the Vet, but more important there may be education benefits for the children or the spouse of a vet. If you apply the worst they can say is, no. If you do not apply you will never know. God bless all Veterans and God bless all those that help the Vets.
I am not affiliated with the D.A.V. in any way except they worked their "Magic" for me and my family. I truly believe were it not for my service and a grateful Nation through the Veterans Administration I would be in the street today. Good luck to you and yours!
