Yes Derxa I've been to AgriScot and I'm completely behind you on this!
The amount of fucking mansplaining happening on this thread is unreal, thankfully there is also a decent number of posters who have completely got your drift.
For those of you that haven't seemed to listen to a word the OP is saying, AgriScot is NOT like the kind of agricultural shows you're thinking of (in the summer, turn up in your pretty dress and pretend wellies, buy lots of local sausages and bunting and wander in and out of marquees full of crafts, and then have your picnic watching the dressage). It's a technical trade fair, it's only of interest to those in the industry and really not the kind of thing you turn up to for a 'nice day out' if you're not a farmer, because chances are you'd be bored witless! Yes it's a bit of social thing for farmers, after all, any time off the farm is a social thing and you'll inevitably bump into other farmers you know, but it's primarily for comparing kit, asking technical questions and really getting into the nitty gritty of things.
It's the equivalent of, say, a tree surgeon turning up to a chainsaw trade fair; all the ins and outs and finer details of the best chainsaws etc, interesting/relevant to the tree surgeon, but not really of any use/interest to Joe Public who lives in the countryside and has a few big trees in his garden.
OP, hope you've managed to sort your quad bike out! As an aside to the JD Gator suggested earlier on, have you looked at the Kawasaki Mule? I've not used one myself but I've heard good things.
