I am sure there is a thread on this already, but I didn't see it in a quick search.
1. What are good objects to lock up to? Stay away from trees. How about sign posts? iron tree guards? iron building racks? meters (how do you get them from sliding the lock over the meter)? are lights okay?
2. Chain lock? U-Lock? What is the best way to use a U-Lock?
3. Do I need a separate cable for my seat?
Any other tips/suggestion?
