DougT,you're right,that cr**py blind works out well,I've a padded cushion in it,covered the top with green PVC cloth and I usually bring with me some warm tea,relaxing!8) Itryed to move a bit when crows were staring at me but no one spotted a twich,what it makes them crazy is that now with the quiet S400 they can't figure out what's going on to theyr buddies falling with apparent no reason(I wait to retrieve the bodyes when they're gone),it's funny when they get more and more angry not finding the threat,he,he,he...
