Trash is not a big issue on the roads and MPT as they do a good job cleaning them in my immediate area. I have stuck pruning shears or saw in my bag to get some annoying branches and such.
I have considered taking ant bait with me to sprinkle around the fire ant hills along the MPT. But thinking that someone might not like the cruelty to another living thing or the use of insecticide prevents me at the moment.
