What every glider operation needs is a designated "official
greeter".
This person is probably the most important on the field. Make it a
real job.

As a relative newcomer to the sport, I say the above is very good
advice.

Most of the places I've visited have been very friendly, but when I
decided to take lessons in 2003 and reported to the nearest soaring
school, I felt like I was interrupting them, even when I announced I
wanted to come back for more! (The rest of the training experience was
great.)
