a jar of peanut butter about every 3 days is pretty average for me as well, although never on sandwiches unless i'm taking it for ride food. if you're buying all natural peanut butter (NO hyrogenated oils), there are definitely worse things you could be eating. at some point i'd like to switch to unsalted all natural, but the store brand doesn't offer that and I can't justify the extra $1 per jar.
to get this thread back on topic...i did 4.5 hours today. found some awesome new roads including a really great climb. it's not even a strava segment which is really surprising around these parts.
