Been a national HOG member for a while now but have not moved to Life membership. I should have years ago when it was much cheaper...
Not sure if our local chapters offer the lifetime deal but have not ever heard it mentioned so would assume they do not.
As for local chapters and discounts, the local dealers have their own discount program but also have some specials for the local HOG chapter members. Both the K'ville chapter and SMHD/Maryville chapters are very active here in East Tennessee. However, I chose not to be a member of the local groups. I was in a home owners association once and did not like it. Went to a couple local HOG meetings and felt about the same as the HOA meetings and decided it was not for me.
