You certainly can GET a ticket. The question is whether it will stick. The answer is, it depends upon the Judge. My suggestion is you take a number of photographs and bring them with you to court and demand a trial and then show them to the Judge and point out that the notice of no parking wasn't properly pointed and wasn't obvious from the direction you were traveling and it couldn't be seen.
Often when a motorist shows that much interest in a parking ticket case, the Judge will give them the benefit of the doubt,
