ViniL@aol.com > Sycamore Post Office (historical)LARapidespost officeUNKNOWNUNKNOWNMelder Thank you so much for the information and GNIS location for Sycamore in Rapides. We had used GNIS --- BUT---never looked for a post office. I gave up but we hit the jackpot with your help. Sycamore, Melder, New Hope with seven other variant names is all in the same location and we found what we needed. Thanks again.
