Rt 66 will be another year now. We have done it maybe 5-6 times. We don't do cars. Every year for the last 30 yrs & counting our trips have been on the HD 2 & now 3 wheels. 48 states & 7 country's. Decided on the northern route as the sw is already hitting triple digits so July would be bad. We need to do 66 in May or June, China virus screwed up this year
