Never enough !
2006 about 90 hours
2007 only 45 hours largely due to weather
2008 so far I've managed 3, again partly because of poor weather but mostly because of a medical problem that stopped me flying from 8 Nov to 11 March. Fortunately now fully fit again.
All logged in my PA28-235
Here's hoping for a good summer !
Cheers
Lysander
