Horwich Railway Mechanics Institute lost a lot of their fan base when they relocated into the Rugby League stronghold that is Leigh.
I worked in Leigh for two years and was surprised to learn that not only did they have a pro-RL side, but also two semi-pro sides in Leigh Miners and Leigh East. You used to see 'Leyther' (term for folk from Leigh) kids walking round the streets with the oval ball.
The slide out of the Conference and through the leagues was quick and there was a lot of hype when the new stadium (council owned) was built and the club changed it's name once again to Genesis. The chairman talked up a big future, but the crowds never materialised with both Wigan and Bolton offering cheap football just down the road. Add increasing rents to pay for the ground and it all spelt disaster.
Big shame really. Not a club that deserved this.
