The Trapper, or the Park City Dark and Stormy, or the ???

While on vacation SD and I occasionally take a break from the hiking (or biking) and scout out the towns and the local hangouts.
After only two days we found that the rooftop deck of No Name Saloon on Main Street in downtown Park City was a great place to hang out,  eat a Bison Burger and invent a new drink. Below on the street the tourist stroll by and the locals ride their bikes up and down the street, repair them, talk about them, etc.  The meter maid strolls by taking photos of offending cars (but never ticketing them), the Historic Park City Free Bus drives by every 4 minutes.

On our second night at the No Name, the waiter, Trapper, informed us that there was a new heifenwieser on tap, a "summer, lemony thing". He brought it, and added a lemon saying he “wasn't sure if it needed it, or what it needed.” After taking a sip, I wasn't sure what it needed either. If you wanted a lemonade beer, then it didn't need anything. But if you wanted a drink, it was lacking...something. A shot of SD's beer helped but not enough. What it needed was a shot of dark rum. Trapper was skeptical but game and so a new drink was born. It tastes a bit like a Dark and Stormy but crisper, cleaner, not so foggy. The perfect drink for those New England summer days on the water, that are bright and clear and not stormy. What it should really be called however, remains unclear.
