I think we veterans on the Forum would all recommend that you scroll to the top right corner of this page and "search" for previous postings on virtually any subject imaginable. Try a few keywords, like buses, or trains, or backpacks, hiking boots, or trekking poles, or sleeping bags....etc. The search window simply says "Search..."
Ivar has done a splendid job of implementing Google to use as the onboard search engine. So, if the subject of your question is here, somewhere on the thousands of Forum postings and threads, you can find it. Have fun wading through all the to and fro debate.
We love answering questions and helping each other. That is what we do, and why we participate regularly. But, in truth, most all basic questions have been asked and answered repeatedly over the years. So, I suggest you try running searches and proceed from there.
No one is trying to dissuade you from asking questions. I am merely suggesting that you use the built-in and very good "self-help" functionality first.
I hope this helps.
