BROMPTOBERFEST East Bay: El Cerrito to Temescal Brewing

Join us for the inaugural **BROMPTOBERFEST** — *ja!* 🍺🥨 Dust off your lederhosen, dirndls, or just your favorite Brompton (traditional attire enthusiastically encouraged, never required). We'll kick off this new East Bay tradition with a proper German-inspired adventure. Starting at **El Cerrito Plaza BART**, we'll roll south — no *schnell* required — to pick up some delicious **Squabisch Pretzels** to fuel the remaining miles. From there we'll cruise the sights (and yes, occasionally the smells) of the Bay Trail along the waterfront, stop for a few *wunderbar* photo opportunities, and continue to the Emeryville Marina before turning inland. Our journey concludes at **Temescal Brewing**, whose very Brompton-friendly courtyard will be pouring Oktoberfest Festbier with UTMOST PRECISION alongside plenty of other beverages and food options. Whether you're celebrating with a Festbier, a sparkling water, or something in between, we'll raise a cheerful **"Prost!"** to good company, folding bikes, and the beginning of what we hope becomes an annual tradition. The ride will be **gemütlich**--**Keiner bleibt zurück** (**comfortably social--no-drop**), and suitable for riders of all experience levels. So grab a pretzel, ring your Brompton bell, and join us for a delightfully un-serious ride with just enough German flair to make everyone smile. *Allez!
