Admittedly I do get jealous of a colleague of mine who leaves work at lunchtime on a Friday afternoon and by 2pm he has taken off in his Microlight from a grass strip near his home, you could never do that in gliding
It helps if you have the right setup. My club is a 10 minute ride from work. My L33 is metal, it is tied out. I can usually be in the air about an hour after leaving work. Still takes time to preflight, push the ship down to the launch point, get water & batteries set up, wait my turn for the tow, etc.
