There is no way I would choose to land my glider in either of the above!
Invitation to a ground loop for certain! I've landed in set-aside, maize that was a bit too tall for comfort, rape that had recently been harvested but lots of twigs still sticking up, pasture with 24 yearling entire black bulls, sheep, freshly harrowed sticky clay, a very steep field with flints, a fairground; also the centre strip at Newbury race course. There was a microlite strip that came close to being a tad narrow, and a helicopter landing pad at Silverstone, that was a bit short. And a field that had no access whatsoever to get the glider out without crossing a ditch....and two different airfields where the folks in charge had locked up for the weekend.
Rule is choose your field by 1,000' agl, preferably near a pub.
