Unfortunately stevomcd speaks the truth, it's quite depressing really. Plus it's a double edge sword. If Inners got a lift and more riders came, would the trails hold up to all the extra riding?
The main reason our summer season runs is so that we can keep/pay full time staff throughout the year. With seasonal work it's sometimes hard to keep the well trained staff that are essential. Winter is a different situation, on a busy day up our hill we have over 1500 visitors in the winter, in the summer it is ~100! Lifts costs pretty much still stay the same, simple math.
Unless someone has a spare few mil to sink into Inners for fun, I doubt it's a viable buisness. However, hopefully someone has the spare cash because I'd love to see more lifts in the UK and Inners is a perfect location. Just a shame they can't have a winter season to cover the costs.
