Some people are jealous of the younger generation and some are just releasing a bit of knowledge I think.
Some are just enjoying talking to interested people but saying the same thing over and over cos it is part of their experience, happens in all walks of life and I do it myself sometimes.
You get to learn who to talk to and those that say the same thing over and over.
I think, for the most part, the older generation are quite pleased that some younger folk are keeping up "the tradition" of things like allotmements because it is, lets face it, a good idea with good reasons(organic)(envoironmentally sound)and also because it is something they understand(better than us youngsters) and believe in.
An interesting thing I heard on the radio the other day is that allotments in Worthing(the smaller sites) have become so popular that they have terminated the waiting lists because they are so long!!!
Good news for the future of plots but bad news for those waitig for a local one!!!............
The mixture of "new" info from A4A and the net versus older generation knowledge is interesting. Learn from both and use what you believe. In the end you live and learn just like they did.

Great! If only I could live till 200 yrs old, I might become an expert!
Fun trying though................
