Let me say first that I have never done this in type of airplanes you are
describing but even if you had an average GS of 50mph it would only take
18hrs which seems reasonable over 3.5 days. I guess the important thing is
whether any day at OSH is different from any other for you (ie do you have a
hotel?) If not, you might as well plan on attending the early days of the
show and, if you are delayed, you can simply attend the later days.

I'm flying from Western Mass to Oshkosh, VFR. I cruise
about 70-75 mph and it's about 900 sm from home to OSH.
Given prevailing wind direction, likelihood of fronts and
afternoon T-storms how many days would you allow for that
trip? I had originally planned 3.5. I d like to be there no
later than Sunday at noon, so I was leaving at dawn on
Thursday. A friend who regularly delivers similar aircraft
over similar distances thinks that's not enough time, and
suggested two extra days (leave Tuesday morn).

Anyone want to comment?
