The Summer release HL numbers are the following:

HL387 14 Mile Point MI
HL388 Gurnet Plymouth MA
HL389 Key Largo FL
HL390 Crooked River FL
HL391 Delaware Breakwater DE
HL484 Whaleback ME
HL726 Sturgeon Point MI

They changed them from what they had them at on a preliminary list, which even caught me, since I had already shot and turned in images of HL390 Crooked River under it's preliminary number a few months ago..
