This is the BEST present I have ever gotten for Christmas, My son Ssgt Paul T Schmitz II, has walked on his own... That's right without any help or aid of crutches, he walked about 25 to 30 feet this was the 24th of Dec. Mark you should receive a picture of it, if you would please post for all to see the miracle.. Praise GOD!!! a very proud & thankfull papa....... Paul sr
