The directions for the Foreign Travel Section (20C, pg. 83) are a little ambiguous. By travel/trips do they simply mean a temporary thing where you return to the US? I grew up in Europe and have been to a ton of different countries and routinely went to neighboring countries for day trips. Do they actually expect me to somehow recall where I went, when, and list something like 50 entries? The form seems to imply that it's merely for short trips. In that case, do I list anything at all (since I made no "short trips" outside the U.S.)?
