I have visited Old Trafford on many occasions. In fact my first match was there against Wolves in 1963. I went to Maine Road two or three weeks later to see City lose 3-0 to Blackpool and felt far more at home. There was something about Old Trafford that I did not like. Like many others back then I would attend some United matches if I couldn't make it away with City. The best period for me at Old Trafford was from 1968 to 1974 starting with the 3-1 win and ending with the Denis Law 1-0 match. City won six of the seven league matches in that sequence and drew the seventh. I haven't been there since. All the matches were for the standing areas and consequently not segregated. I would either stand in the corner nearest to the Stretford End or in the Scoreboard End.
By the time United got back to First Division, I was working away and got out of the habit of attending away matches. It was a long time before City won another match at Old Trafford.
I did once go in the home end at St James's Park. It was for the match on Boxing Day in 2010 when Tevez scored two in a 3-1 win. We were at the in-laws for a Boxing Day party and persuaded a group to go to the match. My Geordie son-in-law bought the tickets for us ...... in the Gallowgate End! Not only that I was sat one row ahead and two seats away from the biggest nutter in the ground. He was huge and 20 stone plus and one of those who would keep his shirt off even in mid winter. It was very scary, particularly as City went 2-0 up in the first seven or eight minutes.
