How does your club handle transient members?

Our club has a small number of transient members that own their own
gliders and only fly with us a few months of the year. It is rather
punitive to make them pay the full club dues every month in order to
offer tows for the month or two that they are in town. Does anyone
have a club membership category and billing scheme that is fair to
both the club and the transient members in instances like this?

In the UK we usually have a category of member called 'country member'
This refers to someone who lives a long distance from the club so that
getting there costs a lot and/or they typically would not be there very
often.
They usually get a cheaper membership because of this and as an
encouragement to come back. A typical price wouyld be 2/3 ordinary
membership
