We drove 4600 km in one trip last summer driving my daughter to the races. We have done half a dozen long drives for her to race a Canadian MX National. Usually with one or both of her siblings. Good times on those road trips for sure.

Not to mention all the driving around Atlantic Canada we have done over the last 10 years racing MX. Like you Clay we have spent many hours together on the road and I would never trade it for anything. She is the only kid at school that can name every highway exit within 4 hours of home.
Awesome goal to have and I hope you achieve it!
