Hi, my name is Olaf Brodtmann and I am mapping a little bit in and around Karlsruhe and then also in the southern part of Lower Saxony. To be exact the northern part of the district Northeim. (nördlicher Landkreis Northeim)

I am using a Garmin eTrex Vista HCx. I did start the whole issue because the doctor said I should do some sport, so I decided to do some hiking :)
