Yeah Crawley and East Grinstead have a lot of Palace fans, i have lived in the Horley area for a while and visit Crawley a fair bit for the shopping etc and i have only ever seen one Brighton shirt to be fair. I am sure there are more lurking about though there must be
I also went to a lot more Palace - Millwall games than you bush and it wasn't always one way traffic believe me. Anyway i know that wasn't the point you were making, and yes i totally agree there are a hell of a lot of Palace fans in Sussex and i am sure there are a few Brighton round here.
