2 WAN Links, Best way to aggregate/LB?

I have 2 WAN links going from my main office to a remote office about 2 miles away:
Primary link = 28 mbps copper
Secondary link = 10 mbps microwave

Currently, if primary fails, we manually failover by physically unplugging/plugging ports at the remote office. Both links are very reliable though, so I'd like to take better advantage of them.

My question: What do you experts think the best way to use both of these links at the same time would be?

I have a 5304xl at the remote site and a 4104gl or a 5308xl at the main office.

The best way would be using one of the dynamic routing protocols such as OSPF or EIGRP. You will be able to do a load balancing and failover with a minimum efforts, but you'll need a couple of routers to accomplish.

You could do a Trunk with the two links

I have been looking at OSPF, but you raise a good point - why not trunk the two wan links on either side? Seems too simple, would the fact that they are different speeds, etc have any massive negative effect?

I think that other option that you could use is Spanning Tree.
