Always pays to work new calls or ones you don't recognize. Today on 20m , I worked W2 who had a 599 signal with beam pointed East. Figured he was just another W2 in NY/NJ. Was I wrong !!! Turns out he was in Idaho ! Unfortunately I had already worked DN13 or it would have been a new Grid.
Sometimes working a call you don't recognize will yield a PODXS # not worked and not advertised. This has been a good day for propagation here in Northern IL and I managed to work J69DS in St. Lucia. Had a nice QSO with him since we worked back in 2008. Told him about my first QSO with St. Lucia way back when St. Lucia had a VP2 prefix. Think he was surprised to have a QSO that wasn't the usual type and more like a ragchew.
Am having fun on 20m PSK31 today. Hope tomorrow is more of same.
