OK here goes, from someone who was in your shoes!!
During the 1974/75 season, my last as a regular watcher of United games, I switched from Old Trafford to Moss Lane. My reasons were different from yours, yours are understandably financial and corporate angst plus the Glazer syndrome, I do reel with shock when I see how much you have to pay now for season tickets, especially for have-to-buy for cup games. During the early to mid 70's Old Trafford was very intimidating and I felt unsafe on several occasions, including trying to get public transport afterwards.
I went with a mate to Alty and from then on I was hooked. I love the fact I can have pint with friends before and/or after the game in the bar. The players often join us afterwards - you will NEVER see that at Old Trafford, they are very amiable and approachable. Like you, we do have much barracking of away fans, but it is very funny with no malice whatsoever, some of it you may have seen on occasions you have been down. The whole atmosphere is great fun with like minded people, and on the ocassions I can get to away games, the Camardarie is even stronger. It does not take long for the club to seep into your blood, but over the years whether they play good or badly the bond becomes two-way. The club as a whole are very close to their fans and are entirely open about their plans and current news items. The websites
www.altyfans.co.uk and also
www.altrinchamfc.com are excellant and informative and a good laugh in the formers case. Other clubs fans often use it for info about their own team, and also to try and wind us up before they play us.
Do come in with an open mind and make yourself known to people, they always are open and friendly. We are not troublesome fans and do not have a bad contigency, but our hard-core fans are very good at finding ways of getting under the aways fans skin and the banter is top-notch. And as I say, it is strong banter but without threats or malice.
One thing, the Alty fans do not take to drums; they give us headaches. We usually try and get one of the centre forwards to hit a football through it during the warm up.
I sincerely hope to see you in the bar or during a game next season, give it a try you will enjoy yourself. I still go to Man U on very odd occasions when I can get a ticket, and I watch every United game on Telly if Alty are not playing as I still have a soft spot for them. But that said, I have no regrets and neither will you in time, you will also save a fair bit of dosh!
Aside from Liverpool and City etc/Arsenal and Chelsea, our rivals are Northwich, Macc Town, and the likes of Runcorn, Droylsden. Of those probrably Macc are the most despised. Suggest it may be fun to go the Alty/Macc game during pre-season. We have not played them for years.
Good luck to you and hopefully see you next season.
