I grew up there and visit my family regularly.
Negatives - I would agree that it certainly has had a few issues with crime of late, my own mother's car being vandalized by kids new to the area. However, that said, I don't think this is something particular to Castlebridge, nor any worse than anywhere else. Also, the planned shopping centre on the edge of the village appears to have run out of steam, and yes, the traffic isn't great into town (but you can drive a long way around Ferrycarrig to get there or hey, get on your bike).
Positives - it does have a distinct village character, with local groups organising GAA, old folks, community action etc. Its only 3.5 miles to Wexford, with lots of pubs and clubs and opera if you like that. Fordes restaurant and pub serves the best pub food you could hope for, and Eden Vale is a gem. The best beaches are closeby too.
When I go back I see great potential. If people rallied together more for better services such as traffic control mesures, foot paths, a manned local garda station (like we used to have in the 70's when it was a sleepy little village) and renovations to Nunn's House, then I think it would be a great place to live.. again.
