Bludo, if you were there, I hope you had fun! If you're in Greensboro NC, short of being in Danville itself, you're one of the lucky few to actually be able to call the Danville AAF Tank Museum your home field - I had to travel well over 6,000 miles to get tracks to dirt, and I have not regretted making the trip six times now.
Now that you're thinking about getting a tank, the first thing is to get in touch with your local tanking group, pick a tank you like, get weekend passes from the Significant Other, and you're off! I can assure you, it is a slippery slope, but you'll have fun every step of the way!
