Craft and lat/long search I've used expression engine but not Craft. I am looking for a CMS more flexible than WordPress. I need to have admins enter location or addresses of meetings and then allow site users search for locations close to them or close to a specific address. Part of the use case is that meeting locations would be posted if the meeting is open or just a contact if the meeting is closed.

Would Craft be a good CMS for this? What about the geo stuff?
Yes, Craft would be a great solution for that!

For the proximity search feature, check out the Smart Map plugin. (Disclaimer: I'm the author.) It allows you to input addresses for each location, then your users can conduct a search to find the closest locations.
