The pub at Hartford Marina used to be a good meet, until it burnt down.
The White Swan at Conington usually has a few bikes, plus the last time I was there, threr was a large group of vintage bikes.
Probably should say that it's not really "the season" for meets/ride outs during the week.
You could also check out these guys... Huntingdon is a little far for a regular meet up (plus I have to get out of the thumbprint of the wife), and Wednesdays with the PMCC - I'm already busy on Wednesdays.

There is also www.themotorbikeforum.co.uk who have quite a few members from our area who meet up regularly.
There must be a few guys on here from around here too. I'm up for rideouts but Mainly on nice sunny Sundays at the moment... when they turn up
