We'll be taking the next steps today in building our knowledge of infrastructure.
After you have devised your infrastructure questions, go online.
1. Write your question here.
2. Pick up someone else's question to answer.
3. Write the question and its answer in your response to the post.
4. Answer at least three questions for complete credit!
PS: It can't be a question on a system you studied--so if you read about subways you can't answer a question about them.
