Yeah, if you work elsewhere I'd use you work phone number and the city. I live in York ME and worked in Kittery ME but we had an official address in Portsmouth NH so I used that s my location. If you don't and you have a friend, or family member, who lives outside of your area you could ask to use their information. Since I traveled a lot my items did not always ship from where it showed and I always told the buyer where the item was shipping from simply telling them my work had me nearer that location.
Of course buyers for high quality bamboo fly rods and reels and high end musical instruments generally are good communicators.
