I have always been an athlete, played basketball, volleyball, ran track, grew up on a ranch. Since the age of 3 I have been on the back of a horse, and that is a true love. No matter if it was work or play. Granted now in life I don't "have to" so when the weather is not cooperating I will keep my happy butt inside.
My kids are athletes, and since my grade school years, I have been glued to football. I love it, my weekends are planned around either college football or pro football. Of course when my oldest doesn't have a game.
I can't say I have a favorite sport. Extreme sports are amazing, traditional sports are amazing. I want to do it all, try it all, enjoy it all.
Started snowmobiling about 15 years ago and that layed ground for a whole new addiction. Adrenaline. Nothing like it.
So in answer to your question, I will sway from favorite to favorite depending on the time of year. I may be a little wishy washy but there are to many sports to love.
