Muni meters are those big-box replacements for the ubiquitous parking meter. You can load up a muni meter receipt with pretty much as you want, and leave your car on a street parking spot in, say, the theater district for roughly 1/4 the price of a garage. The trick is having 6 to 8 bucks in change to feed the muni meter. For this I recommend keeping a stash of Sacagawea (or Susan B. Anthony) coins in your glove compartment. Alternately, going into a local shop and asking for change is a lot less offensive if you ask the shopkeeper for dollar coins. While proprietors may be reluctant to part with quarters from their register, they are usually more than happy to swap dollar coins for bills.
