Dodge,
I work for the state of IL, but only for about 3 or 4 months in the winter. We are called highway maintainers. Basically, we plow snow and fill pot holes, but other neat projects come our way too. The rest of the year I'm hard at work with my guys running my business.
Good luck with your project and as always, we need to see pictures. Mine took about 15 months to complete so at 7 months you are right on track lol. I would have loved to make this one hydraulic since logically that would make more sense. Financially, however, I couldn't reason with buying all new parts and I liked the idea of trying to mimic the old cat crawlers and their design principals. If I did it again, hydraulic would be the plan from the get-go.
I think mine took so long because I had such a blank slate to build on and time was limited mostly to weekends in the winter.
The poker runs are usually done in small towns and are to benefit the local fire department, emt's, or food pantry. Usually there are lots of free beverages, food, and really neat rides that guys make for them. They are good for small communities because they raise funds for good causes, they are relatively safe compared to poker runs on bikes, and they provide unique entertainment for the locals. Besides, a lawnmower poker run down the streets of a big city wouldn't be too easy to pull off.
By the way guys, I'm always willing to help anyone on here build a crawler of their own, so long as individual creativity is respected and not copied. That just takes the respect out of the equation.
