(Undated) -- The D-N-R is urging Minnesotans to use caution with campfires and other types of burning. The lack of rain in the upper two-thirds of the state has increased fire danger. Information officer Tom Fasteland (FAST'-lend) says there haven't been a lot of wildfires in Minnesota so far, but with very warm temperatures we're having, things are drying out. Fasteland says the D-N-R could put burning restrictions in place if wildfire conditions worsen over the next couple weeks. Vegetation and other fuels are drying out in parts of central, northeastern and northwestern Minnesota.
