We don't have a group per say. It would have been fun, growing up, if we had. I just know that homeschoolers seem to stick together more so. And the family my younger sister married into knows a lot of different homeschooling families.
I think I will have a better chance of getting my family interested, or at least my sister's in-laws interested in hypermiling if I can get better mileage with RAVadoodle. This tank will be my all time highest, at over 40 MPG. If I were in their shoes, my interest would be perked with that news.
