Having just returned from Myrtle Beach, I can advise as follows:
Saw good FJ selection of shirts at Barefoot Landing clubhouse.
Martin's PGA Superstore had full FJ collection from Spring in shirts and pulllovers. There were closeouts on FJ performance sweaters ($100 for solid, $110 for argyle). They had some shorts, but no long pants.
Most courses in cooler climates are just getting their orders filled now for spring play. Patience folks....
