The week's question
In December 2024, in the thread "Re: BRK: Why Not XOM?", BreckHutHigh asked the members: "What about the long road trips with kids?" This week it is put to everyone again. The button below opens the small thread re-asking it - read what others have said so far, then give your own answer as an ordinary reply.

I’ll second the rec for Norgate. Not inexpensive though. I purchased their 20 years of survivorship bias free package many years ago put the data in my own database and then for several years regularly updated the data using python get data or yfinace utility. If you don't continue to use the Norgate method of distinguishing between ticker symbols that are reused when a new company replaces an older one that delisted. As I remember the formats at least in the past are not the same but easy to convert. The only problem is yahoo randomly changes their data interface and it sometimes takes a month or two before you have access to data. Have to admit I haven’t been keeping this up for almost a year.
