Heavy equipment operator

So I figure on taking the plunge and getting my heavy equipment operator certification. A bit pricey but it would be steady work for these slow periods in animation. There is a pretty awesome course right here in the hammer.  I just hope it doesnt go like the welding certifications were if your not working you have to requalify every 3 months or whatever at X#dollars per certificate. Have to do some more research first I reckon gonna look into heavy equipment mechanic certification too. EXcavator! Tonka toy fun!
