I used to feel like this but I have to admit I've been getting demoralised lately. Other people going on my land (someone's been shooting and someone else lamping since before the season started, so that what should have been untouched land was low on numbers and the remaining rabbits lamp shy) means it's been thin pickings since the start of the season. Apart from missing the feeling of success which both me and my dogs enjoy, I need food in the freezer - times are hard and the dogs usually make a good contribution to their food bill!
I agree someone else on your on your land is not good
