Whether it's worth your going depends on what aspects of aviation interest you. It's essentially a GA fly-in with a smattering of classic and vintage types, some of which may be of a military persuasion. As a fly-in there won't be any air display, wouldn't want to push the boundaries on that this year, so fly pasts will be the most to expect, even if the Dakota was serviceable.
As for photography, with a westerly wind you get a nice countryside backdrop to touchdown shots and easterly approach lots of hangar clutter that many aren't fond off.
As a local airfield I invariably go, weather depending, and have a jolly good time. Nice folk and nice aeroplanes.
I hope this helps.
