i tried using the Model Railroader Groups page -- http://trc.trains.com/groups.aspx?page=list&type=2&cat=2 -- to look up groups in my area.

i got zero response when i entered either my zip code or state

it also seems that once the filtering has been specified and no responses appear, that you cannot go back to listing groups again.

i also think it wold be more convenient to list all the groups on one page instead of limiting the display to 20 groups.    This wouldn't be so bad if the URL included a page option that could be manually selected to jump directly to a partial list.
