With experience comes the knowledge to only choose / accept sites that have vehicle access almost right up to the hives!
Been there, done that and got the sweaty bee suit!
This little episode had quite a few worthwhile lessons actually. The hives were not actually mine, but a friends - who asked me if I could put them up in my apiary "for a couple of weeks" in mid-March (lesson #1!)
Because they were supposedly short term visitors in catchy weather, I chose to put them 100m along the track to the apiary rather than in the apiary itself (which can get a bit boggy) 200m further on. Sound reasoning until two sleepy March colonies become two large hyper-active June colonies and become really quite intimidating to the families and villagers who share my apiary-cum-field and are forced to pass within 15m of them (lesson #2)
Through a series of Hoffnung-like mishaps, both hives still had two nearly full supers on them - hence the 50kg load (lesson #3)
Arriving unannounced in a large, unfamiliar van at 9pm in a sleepy Cotswold village, driving off road to the bottom of a track and starting loading up did actually arouse a few suspicions and got us reported to someone who keeps an eye on the place (good!!! - but lesson #4 nevertheless)
The cross-country humping and heaving was actually at my friends apiary which is their permanent home and it is in fact possible to drive up to the apiary gate, so it was only a 20 or 30 yard carry really. But it would have been a whole lot easier if the grass had been strimmed (lesson #5)
Although both I and my bees love my apiary, I'm quite envious of the place we took them to. Sheltered by trees from the south west winds; secluded and off the beaten track without being isolated; a few hundred acres of organic farmland to play in; edge of town gardens within easy flying distance - really a small piece of paradise
So it may have been mad, but it was a thoroughly worthwhile exercise, in the process of which I learned all the above, and what travel screens look like. I was also generously given a couple of now-surplus hive stands for my pains, because he has constructed what he calls "old man hive stands" (fixed to short posts) out of pairs of half-pallets on the site; more food for thought
