            Yeah there is always that vibration there but not bad. The plane
I have most of my hours in is a Piper Cherokee PA-28-235 The last numbers
are always the HP. Even though it's IIRC the most powerful engine they put
in the plane It can't haul much. The plane is a 4 seater and you can either
carry 4 passengers and no baggage or two up front and their bags.
              Really safe plane to fly as well because the older ones had a
constant chord wing so tip stalls are very rare. Just needs a turboprop
instead of a recip engine...


                And speaking of flying got back from my short stay in
Burbank. It was 91 and was supposed to get hotter yesterday. Come home to
having to run the heater, luckily had the gas turned on Monday... Long way
to go to get a burger from in and out.
