I would say most American's sense of feet gets fuzzy after about 30, there are very few things that are standardized that size or bigger or that they have ever personally measured out. Yards might be more useful up to maybe 200 or 300 because they have all seen football fields though. After that for most people they go to miles or minutes of travel.

Some farmers might throw in a reference to an acre length that is referencing the 660 foot length of a standard acre (660 feet x 66 feet, or 1 furlong x 1 chain), which is just another way to say 1/8th of a mile.
