Answer: People didn't cross picket lines to show solidarity in an attempt for better wages, better working conditions and various other things that would or could make their lives better.
Explanation: Back in the 50's and 60's when unions were very strong, you were considered a "scab" if you crossed a picket line. You took a chance of being hurt, harassed by other strikers and you showed you were not a team player.
They made teepees because they were nomads. (a nomad is a member of a people having no permanent abode, and who travel from place to place to find fresh pasture for their livestock.) Teepees were easy to set up and put away for traveling purposes. Teepees were made out of stretching buffalo skin over a skeleton of 20-30 wooden poles, all slanted towards a central point and tied together near the top. A flap at the top allowed smoke to escape, and a flap at the bottom served as a doorway.
The excerpt of The constitution of the confederate states gave the historians some insight of Southern Secession. The southern believed that it would be better for them if they leave the Union and became fully separated from the United States
