Loafer, we don't do "rough" in the Fens unless you count bumping into me. I reckon you'll enjoy it.

Of those I personally would avoid Northampton town centre (constant sirebs from the Hospital) Wellingborough (scrotes and noisy whitworths mill) Peterborough Embankment (scrotes)
Other than that it's all good down the Nene.
Across the levels problems have been reported at Whittlesey rec/leisure centre moorings with kids throwing stones - likewise March town bridge.
Other than that I have never heard of trouble in Athy land.
Once on the Ouse there is so much choice you shouldn't really get into bother anyway.
