Most of the cases that do happen (I am talking about Cessna/Piper spamcans, not microlights) need the wings taken off and the thing carted back on a trailer;
I would tend to disagree here, if you have found a suitable field you will hopefully have picked one that is long enough to land in with room to spare and good approaches, most fields like this should not then be a big problem for take off - though of course you should check this before doing so. As far as DVs point about slowing down goes, this should not really need pointing out as it is taught and pointed out in the PPL syllabus during both the bad wx circuit phase and the low flying exercise (though I would agree that it is probably not the most practiced part of the syllabus).
