You certainly aren't the only one, both ST
2 and I hike in long pants all year round, and have been doing so since at least 2004. (In fact, I will share a little secret, ST
2 used to hike in white long john's for many years

) This is not only for the scratching and thorn issue, but also because sunburnt legs behind the knee can not only be annoying, it can be downright painful and dangerous from a dehydration aspect. You also get a ridiculous sock and shorts tan.
We both use Cape Storm Technical pants which are durable (i have been using mine pair since 2005) and have endured a rather extended walk through a thick bramble patch and shrugged them off and numerous long and torturous hiking trips. They have multiple pockets and also zippers from ankle to knee, which means that with a bit dexterity, you can take them on and off over a pair of La Sportiva Makalu's, which are not the smallest boot around. The other good thing is that you can zip these up almost to the knee while hiking and help to vent any heat, a good form of ventilation. They also dry very quickly and can be washed on multi-day hikes and left in the sun for a 10 min or so and will be pretty much dry.
I seem to have a slightly skew walk (from an op on my lower right leg to remove part of one of the three muscles) and my right ankle area has rubbed a raw patch on each inner side of the pants. This has been remedied with two patches of fake leather and they are good to go for another couple of years. I swear by these pants, and would not get anything else. Harsh conditions, bring it on, they rock!
