In the off-season, nothing is really fun. Drivers switch teams and teams switch teams shuffling up the grid for the next racing season. Of course you can tell me there is the NFL and other sports to watch. I can YouTube old NASCAR races. One thing I am willing to try to fill the racing side of the void is watching live dirt racing events that go on during the winter.
I have adopted a newly founded show to watch such as the Walking Dead on AMC. I was never much of a Zombie fan until Negan showed up making the "to me" Zombie storyline much better. Not many television shows I come across I develop a like for. If I do, usually I get hooked on the first season and then it gets cancelled or like it in later seasons and have to play catch up. So I think the universe is just out to torture me on having an enjoyable TV schedule.
Anywho, back to racing. I've always been strictly a NASCAR/Dirt racing person. Sprint cars and modified are top favorite to watch when it comes dirt. Where I live the off-season has neither in winter. The internet has become so great that you can pay a small fee and watch where ever worldwide. YouTube is also a great advantage where you can watch old races that make great entertainment or background noise to get your fix on a cold Sunday.
On another note, we are in College Football bowl season which marks another end to the calendar. Which also a month later the Super Bowl is played hyping up race fans the start of Speed Weeks. Speed Weeks in my opinion is the most suspenseful part of the NASCAR season bringing out the best memories of past seasons. Most of my memories were of the late 90's in Earnhardt's what were your's?
