I don't have too much of a problem sharing information or trying to help anyone catch more fish... in fact I rather enjoy it. Generally, rather than give deceptive information or smart responses... I usually try to size up the person whose asking... based mostly upon the amount of humility they come across with in their approach and their questioning. If they are reasonable and cordial in their approach and their questioning... I will (usually) offer them something useful to try to help them out... but by the same token... also remain perfectly comfortable with my rights to protect my own spots, efforts and work product.
