Johansen family in Moss

Hello again, thanks to the help I have recieved from the posters on this site I have decided to visit Moss where I hope to learn a little more about my GGrandfather Axel Johansen b 1860/1. I would like to ask anyone from this area...where is the first place that I should visit, the Family History Centre, the LDS ? What would be the best day to visit ? I am arriving in Kristiansand Saturday the 14th , I am with my motorbike and camping so please look kindly on the little guy who looks like he, s been dragged through a hedge. I have some photocopies of things like death certificates, obituries etc, that I have, who would be the best person to leave these with. Thanks jim
