>>Some encounters between locals and newcomers have caused tempers to flare. Gregg Alexander, who sells paint at Nelson’s Ace Hardware Store, discovered he could no longer ride his mountain bike anywhere he wanted in the hills around Whitefish. On rides, he has encountered “No Trespassing” signs, and an irate property owner once ordered Alexander off his land. Alexander has found an upside. He reckons the 60-acre parcel near Blanchard Lake Road that he bought in 1997 for $185,000 **is worth millions now.** **“I’ll offload it to one of these dot-commers and go somewhere else,”** he says.
