If you are looking for an interesting road to travel in the area drive FM1431 from Ceder Park to Marble Falls. This stretch of Texas Hill Country road has been voted #1 or #2 in area motorcycle magazines for several years.
Once in Marble Falls stop by the Bluebonnet Cafe for a slice of pie.
If wife is into the old downtown antique type shops she would enjoy that in MFalls as well. There are plenty of places for the hubby to hang out while he waits. I've spent many hours holding down a bench eating ice cream there.
