In an effort to assuage your analism, pants, here ya go:
My new GPS doesn't yet talk to me (Sena issue hopefully to be resolved soon), so I didn't much pay attention to it or keep a record. BUT . . . I live almost exactly 2 miles further from Mariposa than neighbor Doug (bugnatr, who used to be my spider killer before he retired from arachnid supression).
So I did a check on Google Maps and came up with something under 200 miles each way (I went down and back mostly on 49, with down including Salmon Falls and Latrobe Rds., but cannot get it to calculate that route like I once could with my beloved but outdated MapSource program). Having had marginal remaining tire life for YFO (I only installed new tires in the last couple days), Teri and I only did Tyler's Friday ride into the park. So, maybe put me down for ~500 miles total, which more or less matches gasoline usage.
