Again, it was really peaceful then suddenly storm hit us!! 30 to 40MPH from the upstream that pushed us too quick. Then we got another gusts from downstream with 70MPH (gustimated?). I thought my boat might get flipped over but fortunately storm left as alone.
So lessons learned. "If you don't like Montana weather, wait 5 minutes". Now it's opposite " if you like Montana weather,watch out in 5 minutes!!"
