I always wondered this myself Sandy. It sounds like Met was trained on blended curbs. Honestly I prefer blended curbs they are so much easier than the curbcuts that have a bump on them to get over. We have both kinds where I live now and even areas where there are no curbcuts despite there being a sidewalk so Met has to walk me on the shoulder of the road. I really hate that when traffic is around because they also park their monster jacked up trucks on the shoulder...arg Karyn and Met
