Can't answer the "indoor" question. I don't think I've ever had that option. As for grass... it isn't available most places I camp. Pine needles, redwood dust, and dirt are my most common options. No grass here, for example...
That is ADffffffffrigginventure. That man has some cold stones right there. This is front page stuff!! Cheers.
Herer are a couple from a trip last summer - 6 weeks on the road and in the tent. Camping on the side of the startline at Hockenheim for the Nitrolympix drag races. (I was crewing on a Pro Mod car). Italy, in the hills above Trieste. Montenegro, down near the Albanian border
The Guzzi V50 Nato is my brother's, the Honda CB SevenFifty is my wife's and the BMW R1150GS was mine (nowadays I ride an R1200GSA). This picture was taken during our annual Ardennes weekend, 2012 edition.
