Alot of stuff is not easily observed out of town
Outside of maybe Baltimore and South Florida Cholov Yisroel is not available, MAYBE you will be lucky to get milk, certainly not Ice Cream or cheese
Kosher items in general are harder to get out of town. In NY Bread and Ice Cream are all Kosher, this is not the case out of town and some items kosher in NY are not kosher elsewhere.
You also might be subject to issues involving other religions. In Ny other religions sort of keep to themselves. This is not the case elsewhere. Ive seen bible quotes on buildings 50 ft high crosses. People talking about their savior every other word
