Either way is a risk. Either you have the beans sent to your house, or you tell a friend about your grow and have the beans sent to their house.
I opted to have the seeds sent to my home. I decided that that was the lesser risk. Not that I would expect my friends to rat me out, but when you tell other people, they just can't seem to keep their mouths shut. I can't tell you how many times casual friends have said something like: "My brother grew this." or "I have a good friend growing WW" or even that they themselves grew it.
Seeds that are seized are generally seized by customs. I have never heard of anyone who got popped because they had seeds sent through the mail to them (I can't imagine that customs gets too excited about someone who ordered 10-20 seeds). However, many people are busted because they shared their secret with the wrong "friend".
