Thanks to all for the advice.

Turns out I only got on the road one of the 3 days. Wednesday was too windy and Thursday was too busy since we were also packing to leave. On Tuesday I got 25 miles in. I was aiming for 30 but turned around earlier than I intended. I rode east on 98 to 283, then down to 30A and back to 98.

I didn't really like riding on 98. Although there was adequate bike lane and shoulder, I felt pretty exposed to all the traffic. 98 is a very busy road, and the speed limit is 45 to 55, so there was lots of high speed traffic traveling very close to me. Also, parts of the bike lane and shoulder had debris or gravel, so I had to steer clear and occasionally move out in to the regular lane.

I turned south on 283 and then realized there was no shoulder. But after a short while I spotted the path to the east of the road and hopped on to it. On 30A I started on the path, but quickly discovered that it does have its share of slower cyclists, children, joggers, dog walkers, etc. At first I was just going to put up with it. But when I came across a backhoe that had been parked on the path (due to work on a nearby bridge) I decided to move back to the road.

Apparently riding on 30A comes down to "pick your poison": take the path with lots of slower users (including walkers and joggers that spread out across the entire width of the path) or take the road with no shoulder. Every serious rider I saw was on the road. So that's where I ended up. Drivers were very courteous and I had no complaints. I did hop back on the path briefly when a pickup stayed behind me refusing to pass even when there was plenty of room. I daresay the drivers were more courteous than the trio of riders I saw who blew right through the stop sign at Old Blue Mountain Road without even slowing down. No wonder drivers hate us.

It was not the best Florida riding I've done, but it was still a good ride.
