CAn someone please tell me what the letters next to the towns and shelters mean on a list
for example
Fontana dam has R (E-5m, G, f-6m, L, f) (W-2m, PO, G< L, M, O, cl, f)
I know that W - water and PO - post office
but what dose the others mean
every thing I have that uses that system does not tell you
thanks for the replys in advance
