What do you mean by a "fish in". Is that a 24 hour session or something? in which case, you might find Marsh Farm a "no-goer", co's I don't think they allow all nighters there. If its just a competition, I might "ave a go" just to make a stand for disabled anglers anywhere. My wife would also probably fish as well, so that's two of us.
p.s. I am not wheelchair bound or in need of any assistance, but only have the proper use of one arm.
a fishin is a chance for people from the site to get together for a social meeting, meet up somewhere fish a bit, have a bite to eat, but most of all meet the other people on here and have a good laugh.
Marsh Farm is a cracking lake but you could struggle a bit as winter gets nearer. The crucians are certainly a good size there, difficult, but when they do decide to feed they're often very big fish.
Good tench and silver fishing as well.
If it has to be in the next few weeks (and into December) think about Willow Park and Gold Valley (both near Aldershot) and Willinghurst (near Guildford). All three are "commercials" and hold a very big head of fish (not all carp either) and usually fish pretty well in winter conditions (particularly if it's consistent).
You might think about Longshaws, between Herne and Sturry. Top class Roach fishing, plus loads of Carp, Tench and other species. Every year Roach of up to 3lb+ are caught there, with loads between 1 and 2lb. There's a good pub just up the road, and if non fishing partners fancy a day out, Wildwood Reserve/Zoo(mostly UK animals) is also just up the road, about a mile or so.
