Just a heads up for anyone on the lookout for overalls, work clothes and the like that would be useful on the WW&F, I've had great luck with All Seasons Uniforms out of Woodstock, Il. Not only do they carry all sorts of workwear, they carry at least 5 different brands of bib overalls- at least 1 (roundhouse) is American made.
They have great customer service and are a pleasure to deal with. They also tend to offer a really good (if not best) price on what they carry.
Their number is 847-952-9860. You can also order online.
