When I first bought my Mooney I was flying back from Texas. I got a
clearance void time from a remote airport and took off. At about 300
feet I lost the airspeed indicator and the altimeter. I was just about
to enter the clouds. Since the terrain was flat and I have the Garmin
moving map I elected to make an emergency return to land at 300 feet
(rather than enter IMC). Turned out to be bugs that had climbed up into
the pitot/static system. It was interesting landing a plane I'd only
landed once before and not having any airspeed. It was a somewhat firm
arrival.

You are a brave soul. You wouldn't catch me taking off into IMC in an
airplane I'd only flown one time before. Now you know why.
