I think we got very lucky with this most recent stretch of events. Each day had at least a couple targets/storms to spread folks out, and most events were relatively low-end (mostly SPC Slights), so that may have helped not draw too much attention. If the 26th had verified in southwest/western Kansas as many chasers had been hoping, we may have had chaser-jam incident. I think a majority of chasers, including myself, were in Scott City, KS or very close to that location to start the day. Of course, a chaser-jam from that setup is pure speculation, but it has been a while since I've seen that many chasers in one spot.
As for my personal experiences, I didn't witness anything out of the ordinary during my recent 11-day stint in the Plains. There were a couple of incidents of chasers unnecessarily pulling out in front of me and reckless passing, but I'd contribute that to typical careless behavior rather than a pent-up chasing desire after the crappy last year. I saw others on Twitter reporting similar incidents. I did have a LEO approach me and several other chasers along a stretch of road on May 24 as we were watching the initial storm north of Leoti to say that they had received a report(s?) of chasers running stop signs in the area. He warned us to not drive recklessly and that if we saw a chaser doing so to report them, but again, I think this is base line/normal, sadly. From a traffic and driving stand point, my experience this spring was very mild compared to other stretches/events.
