Merriweather attracts a variety of big-name acts and is a great place to catch casual summer concerts--throw your blanket down, relax and listen. Ticket prices are reasonable, but food and drinks are ridiculous. Fortunately you can tailgate in the lot before the music starts. Bathrooms are limited, too. If there are a few opening bands, bring something to do in between acts, it can take a while. And if it's a popular band, go early to stake out a good spot.
