My son and I are planning an adventure leaving July 3, Minnesota to Idaho to ride some of the BDR and back. We have 9 days total to do our adventure it will take 2.5 days each way (MN to ID) leaving 4 days to ride the BDR. We are thinking of starting where section 2 begins which is at Pine to Yellow Pine. My question is if we ride at a steady normal pace doing some but not to much stopping for sight seeing how far will the end of the 4th day on the BDR take us? Thanks for any advice or info.
