You are what you eat on the road, especially at the beginning of the week. Tasting exotic treats you can't get back home whets your appetite for travel, but beware of overindulging or lacking caution, both of which can slow you down. Just take whatever precautions are necessary for your destination: sticking with bottled water, for example. Be careful in your interactions with people from wednesday through friday as well; what they say may be different from what they mean. A discussion about religion or politics could impact your ideals this weekend, but remember not to be too blunt: travel is about respect.
