Sounds like you haven't been close to any of the above listed places then!
Or is a good away day credential based only on it being convenient to where you live?
I've been to plenty of away games thanks, I've ticked off 115 grounds across the country. As much as I don't share you're enthusiasm for going back to town's and grounds in this league, including Colchester which is the most convenient place from here, I'll still get to as many as can get to.
