I think it is possible to go to the 'members list' on this forum and then use the pull down menu "search members" and click on advanced search and then just choose parameters you would like to search for.
While I haven't searched this way myself, it does look like this might be a viable option.
It looks like you can search by plane model and area etc. If this works then it seems like you could send a PM to the owner and see if you can set up a visit in the area that works the best for you.
Good luck.
