Hello from Atlanta, Ga.
The YMCA is a great place to shower---but you must have your YMCA  ID card,
and bring a lock and towel.  Some Y's  have free towels and loaner locks,
some have no locks,
some no towels.
Local Rec centers may have free showers, but some charge $1.00 to $3.00 for
a daily membership.  Once again bring a towel and lock.
I might mention the large downtown Vancouver Canada YMCA---both it and the
downtown YWCA have residence rooms for about $30.00 US per night.  The YMCA
is a wonderful clean and nice place and is across the street from a Hyatt
with $150.00 per night  rates.  The Canadian Y's honor US memberships, but
not all of their Y's have residence halls.  Some have off street parking for
a Westy (vanagon content).  Here's to clean living!
