I'm pretty sure Foel, Hopton, Bringewood, Caersws, Rheola, Mynydd Du and even Moelfre etc didnt cost hundreds of thousands to 'build'. They also get more interesting as they wear meaning minimal repair costs. There may be a smaller market for advanced trails however the setup and maintanance costs are minimal.
I gladly pay many times the asking price of Welsh trail centers to ride these venues due to the quality of these 'budget' trails. even without uplifts. Add in a weekend of uplifts or racing for around £70 and you've got a sold out venue for the weekend.
I have deliberately left out Cwmcarn BMX track due to it bein designed to be maintainable to an easier standard that will attract a wider range of riders to make the full time uplift service viable.
What gets annoying is when decent trails at trail centers are blocked off, destroyed etc in the name of progress then you get asked to subsidise their tame replacements. I can understand the risk management aspect of these trail but I'm never going to agree with it.
