Well, considering you would like to make load-balance, I suppose the topology is a triangle like one, I mean single router in one location (A) and two on the other (B).
Naturally there is no problem when load balancing from A to B (assuming you have equal costs) (you can achieve this with almost any protocol), however, B to A actually needs variance (unfortunately not available on OSPF). Here EIGRP can be considered. Otherwise, you may try to share the load with the help of static routes you had mentioned but this is not the best way to do it.
