It's happening again.  After a week of indoor biking, because of the poor weather conditions, I finally was able to do a ride outside.  But, as it occurred last year, Canadian fires are causing nasty weather conditions in the area.  I decided to do my normal 30 mile ride and when I was finished I had this nasty taste in my mouth.  A result of the poor air conditions.  Good weather conditions will prevail next so looking forward to future outdoor rides and ultimately a century to Champaign.
