heads up all newbies, including me with three weeks on ace350. i came across city park field supervisor while MD'ing. he was very polite informing i must have permit to MD in the city. he told me i could be cited without permit. i agree with him and i was so glad he told me this. he also told me his patner was observing me in their truck while i was digging. i was relief when he told me i'm doing a good job putting the area i worked in original condition. man! you never know who's watching. he told me who to see for the city permit, without fee. also i told him i'm in the lost stuff organization do volunteer work for community if any person lose their jewelry or something of value. both were very please to hear about our organization volunteer work. now i got the whole city parks to myself to MD without anyone on my back. one more thing, don't carry full size shovel. that will turn off any park supervisor. yes, each MD'er should look into their city rules just to be on the safe side. i will carry the MD's permit in my wallace once i get it from the city clerk. just want to share this, be kind to the city clerk and the park staff. ace350/pro pinpointer
