I realise that I'm lucky people are prepared to put on model railway shows for me to visit. But, time after time, the following things irritate me.1) How to get there. So long as an accurate postcode is supplied Google maps or a GPS will get me there. Many organisers put out signs "on the day" and many are very good. But too often they don't appear where you need them (we aren't all locals and we don't all use GPS) and the direction they point is unclear. 2) Parking. Many halls have small car parks. Where do I go when the park is full? Again, some organisers are very good with marshals pointing out empty slots. Some go so far as to make arrangements for overflow parking. Just leaving me to clutter up local streets is asking for conflict with residents and pointing me at a supermarket car park which has civil enforcement of stay time (no I've never had a so called fine) is stupid. Start by at least clearing the car park of all trader, exhibitor and helper cars before the public arrive. 3) Pricing. Thank you for offering concessions. Now, who qualifies? Unemployed - how do you want me to prove it? OAP - define OAP. Old enough for a bus pass? In receipt of state pension? Over 60? Over 65? And bear in mind all the changes that governments have already introduced and will continue to introduce to increase the age at which you receive the state pension. How old is a child?
