Waist high in nettles, with areas of brambles and couch grass mixed in for good measure. Our site was apparently a Victorian glass tip, so vast quantities of broken glass and bottles (mostly seem to date from around the 50s-60s though, so never any interesting ones :-\ ) I get about 2 sacks of perennial roots and 1 of glass per sq metre dug.
Oh, and rabbit holes in the middle, and assorted trenches and ledges.
Then you spend hours digging, get a nice, clear bed and start planting, and some inconsiderate wotsit takes a short cut right across it to reach their allotment.
Ever feel like giving up?
Have managed to grow broad beans, onions and potatoes without him destroying them yet. :)
