Yea, mostly crummy tar and chip roads, well actually, mostly just tar, Ha. which is why during the summer months you want to have your riding completed by late morning. Your observation reminded me of an organized tour across central Illinois several years ago. On one day a bunch of riders got a late start and were forced to ride into the middle afternoon after the roads had heated up so badly. The tar ended up sticking to their chains, derailleurs, brakes and onto their frames. The tires were so caked in tar and gravel that you couldn't pedal as everything was seized up. Needless to say they had to be SAG-ed into camp by the dozens. Their tires were un-ridable and so all the bike shops in a huge radius drove over to deliver new tires and chains so these people could complete the tour. Fortunately my partner and I knew better and were done riding by 11AM.
