You fly to one's with numbers eh???
The trickiest part is often finding them. I flew out one for about 10 years.
best bit was being able fly to any kind of approach you wanted, not having to wait behind others on the ground or fly behind the chap killing 2 birds with 1 stone by combining his nav with his circuits
(It was solely used by the owner of a/c)
to judge the wind we used the time old method of chucking a handful of grass in the air and hope by the time we came back it was still more or less coming for the same place.
but it was 600m long so there was enough room to play with if you did end up landing with a slight tail wind.
