Got up early because I wanted to get some miles in before it gets blazingly hot this afternoon. Rode to the office and dropped my backpack in my bike locker. Headed out to the bike trail for some non-motorized traffic intervals. Either a bear or a human a-hole dumped garbage cans and broke bottles all over the trail. Thought I'd managed to avoid the glass but back in midtown I heard a whiss-whiss-whiss. My front tire was getting soft, but the sealant I'd put in these tubes was doing its job. Gingerly rode the remaining few blocks back to the office. I guess I'll have to replace that tube before starting home at the end of the day, but no biggie.
