Can anyone tell me about these two sites:

U.S. Life-Saving Service Heritage Association , P.O. Box 75, Caledonia, MI 49316-0075
$25 for Life-Saver membership

U.S. Life-Saving Service Heritage Association , 158 Polpis Road, Nantucket, MA 02554-2320
$35 for Life-Saver membership mailed to Treasurer, USLSSHA, PO Box 1854, Anna Maria, FL 34216-1854

Except for mailing addresses and membership $ amounts, they appear to be for the same organization. Is one simply a page with out-of-date information or has this group had a schism, with both successors to the original operating under the same name but in different states?

I am interested in joining, but want to know first if one of these is not legit.
