Like most vegetables, cucumbers are tender and tastiest when harvested young before their seeds are fully developed. Slicing cucumber varieties are generally ready for harvest when about six to eight inches long; pickling types at three to five inches.
Headlights on âupperâ or âhighâ beam let you see about 350-400 feet ahead. 400 feet is your approximately stopping distance when driving at 50-55 mph. That is about the length of a city block. In other words, high beams let you see twice as far as low beams.
To establish proper visual lead time on a city street, you should be looking at least 15 seconds ahead, which will work out to be at least a block ahead (about 600 feet). On the highway, you should also be looking at least fifteen seconds ahead as well, which works out to be at least one-quarter of a mile ahead.
