Dear chad,
As long as you have the opportunity to take the waders out and air them out in a hotel room you should be fine. Toss a dryer sheet or two into the trunk, or better yet, get one of those stick-on air fresheners for your trunk if the smell gets too bad, or you if have drive with a client, or your boss.
I spent over 10 years as a salesman in upstate NY. I had to wear a dress shirt and tie. But I stopped often to throw a cast or 50, and had plenty of people along Catskill and Southern Tier Rivers blow their horn at me and wave, or laugh. But no one I ever met for a sales call ever accused me of fishing. Handi-wipes helped for that!
Have fun man!
Regards,
Tim Murphy
