A fair bit of rubbish spoken in the last few posts imho.
Let's face it, no-one wants to sit on the bank looking at red, yellow and blue tents. It's bad enough with all the khaki/olive and camo shelters lined up along the bank. It's supposed to be a fishery, not a campsite. These places are so busy now we can at least do our tiny little bit to blend in to the countryside by purchasing a green shelter. You can pick them up for the same price as standard tent if you look around.
They're not imo. In fact I'd say you'll find plenty of anglers that snigger at this camo revolution that seems to be happening this past few years. I am more than happy with my olive brolly but, if we talk logically, if anything should be camouflaged it should be the biggest/most obtrusive thing...... which is the shelter.
Each to their own at the end of the day but I can think of nothing worse than sitting staring at brightly coloured tents all day.
