SLA Ping Tracking on 3750 SMI

Question

Hi -
My network is as follows:
Two Cat 3750 running SMI with HSRP at a main site (let's call them s1
and s2 - w/ s1 as the primary).
s1 is connected to a remote site via metro enet to a router r1
s2 is connected to the same remote site via a router r2 connected to a
T1 to r1
r1 and r2 are 1700s w/ IP feature set.
At r1, my default route is to s1 w/ another default route to r2 as a
backup with a higher metric.
Here's what I'm trying to accomplish (this is mainly going to require
configuration on r1 and s1 I think).
The metro enet interface on r1 and s1 NEVER goes down, even if the
circuit does. As a result, I was using SLA tracking on r1 to ping s1.
Works fine - the route fails over and back (although slowly on the
failback).
Problem is on s1. With SMI, how do I say: route traffic to the remote
site via s2 if r1 is not pingable?
I set up SLA monitoring (rtr) on s1, but the tracking functionality
doesn't seem to be in the SMI.
I know this is easily fixed by running EIGRP, but I'm trying to NOT buy
the EMI.
Thanks
