Avodah Zarah 12: Traveling and Leniencies

Starting with a new mishnah from the previous daf.... A festival for the non-Jews in the next town can allow for business if the celebration is not right there. Unless heading for the city is the only possible path, in which case, observing the festival seems to be the destination. Plus, there's a lack of concern that the Jews and non-Jews might intermingle their cooking utensils - a rabbinic prohibition, in an case -- for kashrut as a parallel case to the idolatry. Also, a traveler to a place where the festival is taking place - with various concerns about appearing to bow before an idol. Plus, a concern of "danger" - so drinking, for example, directly from the water source is not recommened.
