The extent of our "trip planning" mostly involves what direction we are going and would like to end up at. Then,every day we get up and sometimes we decide to go right instead of left. Some days we will set out to go 200 miles and after going 10 we see something we want to stop and visit and that is our day and sometimes our week.If I hear about a great trout stream I can get to that we can dry camp next to the stream for a few days,that is what we do.
I know planning is necessary if your time is limited. However,I just love to go and make a new decision every day with the info we have and get while traveling.Sometimes our three week adventure turns into a eight or more adventure.
