Kyle, my girlfriend and I went to England over christmas for the boxing day-new years day games (4 in 12 days for most teams). We were able to see a london derby, fulham v west ham, at Craven Cottage on Dec 23. Then we went to Manchester to my Mecca (old trafford), we saw 2 games there, United v wigan on boxing day (dec 26th), and United v reading on dec 30. You want to talk about atmosphere?! Try 77,000 fans. The highlight of the trip was through some connections, we were able to score director's box tickets to St. James' Park (Newcastle) to watch Newcastle v Man United on new years day. ABSOLUTELY AMAZING!! We even met, and had a pint with Sir Bobby Charlton in the Director's box lounge!!
Anyway, all 3 grounds we went to were unbelievable in their own way. If anyone is thinking about taking a trip, that is the time of year to go! You will never be able to see 4 premiership games in 2 weeks during any other time of the season.
