Modern Western feminist history is split into three time periods, or waves, each with slightly different aims based on prior progress. First-wave feminism of the 19th and early 20th centuries focuses on overturning legal inequalities, particularly women's suffrage.
In general, non-breakaway objects should be located 7 - 15 feet from the edge of the travel lane, depending on the type of road. If possible, a mailbox should be located so that a vehicle stopped at it is clear of the adjacent travel lane. (Exceptions may be made for very low-volume, low-speed, local roads.)
According to standard postal service codes, a mailbox should not sit any higher than 45 inches from street level. Place the post in the hole. Level it and attach two support beams at the center to keep the post standing up straight. Place one at the side of the post, and then add another to the back. This will ensure the post does not move while pouring the concrete and it remains level while the concrete is drying. Pour the dry concrete straight into the hole leaving 3 to 4 inches of space from the top of the hole.
