I personally don't find fishing posts to be of any value..
Similar to messages, "please let me know when you're coming to ...."
Most times when you do something else is going on in that persons life that they can't meet with you..
This is why when I travel I always plan it around a concert.. Friends & family time.. Etc.. It takes less stress off of making money and makes it more enjoyable all around. My attitude is more positive.. I don't just sit in a room waiting for someone to call, etc.
