>>1396009yesss... i have the same feelings, where i live spring is one of the best times of the year to ride.
i mostly ride on rural dirt roads, but as you say, once harvest starts, it can get a bit annoying.
i also enjoy the fact that you get more daylight hours, so riding after work is super relaxed and you get to see beautiful sunsets. i'm not into bikepacking (yet) but i do some biketouring and you can ride more hours, or make a nice lunch/nap brake at noon and still have a lot of time to ride.
where in the southern hemysphere are you, anon?
