CashKey, Denver Department of Public Works
How to thwart those pesky, persistent meter people: Get yourself a CashKey. The handy card key, electronically programmed and available from the City and County of Denver's Department of Public Works in replenishable amounts of $10 to $100, fits on your key chain and is debited a quarter each time you insert it in the meter. You also pay an initial key deposit of $15 that's refundable if you return the key. No more fumbling for change or constant meter-feeding. The only catch? You still have to find a space. Good luck.
